  MY NAME IS OWEN BROWN.

  Normally, I live in Pinewood Bluffs with my friends Jon Doyle, Dana Runson, and Sydney Lamberti. But normal wasn’t normal anymore, and hadn’t been for weeks. Take right now, for example. We were clinging to giant mythical horses, flying a hundred miles an hour across the freezing skies to Iceland.

  Iceland!

  And since we’d never been encased in ancient Norse war armor or ridden flying horses, we didn’t know that cold wind whistles into iron helmets and freezes your eyeballs.

  But we were finding out.

  “Stopppppp!” I screamed.

  “No time!” shouted Miss Hilda, the armor-clad lady flying ahead of us. In her mythological life, Miss Hilda was Doom Rider, one of the famous Valkyries from Norse mythology. They were the three daughters of the supreme Norse god, Odin, and they chose which heroes died in battle. So far, they hadn’t chosen us.

  Oh, yeah — in their other lives, the Valkyries were the lunch ladies at Pinewood Bluffs Elementary.

  “Look there!” said Miss Marge through her silver helmet, pointing to the earth below.

  Blinking the icicles from our eyes, we saw a white island in a frozen sea.

  “Iceland!” said the third warrior lady, Miss Lillian. “Land of the Norse gods!”

  The Valkyries sang their favorite tagline — “Hoyo-Toho!” — and all seven horses dove like missiles seeking a target. Hanging on for dear life, my eyes shut as tight as I could make them, my mind spun with the events of the last few days. They weren’t pretty.

  First, the evil Norse god Loki stole Dana away to the Greek Underworld. Then Sydney, Jon, and I snatched the famous Lyre of Orpheus from a museum and rescued Dana. Next, Loki brought the giant, one-eyed Cyclopes to the power plant in Pinewood Bluffs to make him a suit of magic armor. Once his armor was complete, he stole a half-dozen fire monsters from the Babylonian Underworld and set them loose to burn up our planet. Oh, and then he turned around and had Dana’s parents kidnapped, sent them to the Norse Underworld, and started searching for something called the Crystal Rune.

  All so he could overthrow Odin and take power for himself.

  Miss Marge’s booming voice cut through my thoughts. “Odin’s messengers approach. We fly to them!”

  As the Valkyries urged their giant horses to fly faster, the air echoed with a long, eerie call. Two ravens — one white, one black — circled out of the sky and joined us.

  “What news do you bring us?” Miss Hilda asked the birds.

  The ravens fluttered alongside her, chattering and clacking their beaks. A moment later, they flew back into the clouds.

  “Loki has left the Babylonian fire monsters to complete their task in Pinewood Bluffs and beyond,” said Miss Lillian. “He has come here to the north. Alone.”

  “This is good, right?” said Jon. “I mean, not the fire monsters part, but the fact that Loki’s still up here?”

  It was good. Ever since Loki’s ghostly Draug warriors had kidnapped Dana’s parents, Dana had worried about her parents being trapped in the Norse land of the dead, a creepy place called Niflheim. The upside was that the Crystal Rune was still in our world somewhere — and apparently, only Dana knew where. So Loki wasn’t about to harm Dana’s parents. He needed them as leverage.

  At least we hoped so.

  “We need to find the Crystal Rune as fast as we can,” said Sydney. “Those fire monsters will burn our world to ash.”

  The horses leaped forward, making a beeline for the coast of Iceland.

  “There’s an old legend about the Crystal Rune being buried near the island’s northernmost volcano,” Dana said. “We’ll only be able to bargain with Loki if we have the rune.”

  So we knew what we had to do.

  Find the Crystal Rune.

  Stop Loki.

  Rescue Dana’s parents.

  Oh. And stay alive, too.

  That was a big one.

  Just as we began to make out the shape of Iceland’s mountains below, the air fluttered behind us.

  “More birds from Odin?” asked Jon.

  “No!” cried Miss Hilda. “Ghost falcons! Dive! Dive!”

  The Valkyries slapped the reins and drove their horses downward. Ours followed. I wasn’t sure whether the ghost falcons spotted us, but they kept flying due north — exactly where we were heading.

  “Loki’s falcons will join the battle for Odin’s throne,” Miss Lillian said ominously from behind her helmet. “Their appearance means that Ragnarok is near.”

  Ragnarok is a word in ancient Norse that means the end. The Twilight of the Gods. The end of the world of Norse divinity. I couldn’t imagine what that might look like, but I knew it was bad.

  “That’s two signs,” said Dana. “The Fires of Midgard are one of the signs predicted before the overthrow of Odin, too. We just saw that happen — all of Pinewood Bluffs was on fire. Loki’s making sure all the predictions happen.”

  We dipped out of the clouds over a vast body of frozen water. It looked like a lake, but it was actually the opening of a humongous volcano, miles across.

  “The legend tells us that the Crystal Rune was hidden by Odin himself,” Dana said as we circled overhead. “But there was one book that revealed that the rune was in the crater of the northernmost volcano in Iceland, ‘buried by sound and silence.’ My parents burned the book to keep it from Loki, but they read it to me over and over. I guess they knew I’d need to find the rune someday.”

  Dana drew in a long breath. I couldn’t imagine how worried she was about her parents. If my family was in the Underworld, I’d spare nothing to get them back.

  Tiny villages clustered on the south side of the volcano below were dwarfed by the enormity of the crater. Soon the horses landed at a fast gallop on the rim.

  “Buried by sound and silence,” Sydney repeated. “It figures there would be a riddle attached. Nothing ever comes easy when the end of the world is at stake.”

  “I hope we don’t get buried there ourselves,” said Jon. Silence. He added, “Don’t everyone laugh at once.”

  We dismounted. Together, Sydney and I helped the Valkyries hammer an iron post into the edge of the rim, attach a thick rope to it, and lower the rope down the inside wall of the crater.

  “This volcano is extinct, right?” asked Sydney.

  “Usually,” said Miss Marge.

  “Usually?” said Jon. “What should we do if it starts to get active again?”

  Miss Hilda peered into the crater. Without a hint of humor, she said, “Remember the good times.”

  Sydney blinked. “All ten years of them.”

  “Take these torches,” Miss Lillian said, unpacking two sticks from her horse’s saddlebag and lighting them. “We must go. Odin needs us. Good luck.”

  “Wait,” said Jon. “Any other words of advice before you go?”

  Miss Marge looked sternly down from her horse. “Always remember …”

  “Yes?” I said hopefully.

  “… the end i
s coming!”

  “Thanks,” Jon said. “Thanks a lot.”

  With a whirl of wind and a scatter of ice, the Valkyries rode up into the sky again with their horses.

  We looked over the rim to the deep crater below. Steam and fog rolled up from the abyss, so we couldn’t see what might be down there. Eerie noises echoed up the rocks. Creaking. Fluttering. The clattering of rocks down the side and onto the frozen surface of the lake.

  Jon shook his head. “Oh, man …”

  “When the volcano erupted a few years ago, a net-work of ancient mines was uncovered,” said Dana. “Scientists haven’t explored them all the way. Which is good for us.”

  It was hard to believe that any of this was good for us.

  I held on to the rope and lowered myself onto the steep path that twisted around the inside of the volcano, using my sword as a snow pick to steady myself. Soon we were making the long, winding descent into the crater.

  A slow hour later, we stood together on a narrow lip of rock, staring into a ragged black hole in the side of the volcano and wondering.

  “The mine entrance?” asked Sydney.

  Dana nodded.

  “How inviting,” Jon added.

  Inviting or not, Dana and I stepped inside first, since we had the torches. They didn’t help all that much. Darkness closed around the flames so tightly we saw only a few feet ahead. We had to crouch really low to avoid getting our heads sliced off by the jagged rocks hanging from the ceiling. Step-by-step we pressed deeper into the mine, until the way was nearly blocked by huge, stringy cobwebs.

  “If a giant spider attacks us,” said Jon, “I’m going to be very upset. Of course, I’m starting out pretty upset, so you might not be able to tell the difference. By the way, these mines are abandoned, right?”

  Dana burned the cobwebs away and squinted into the darkness. “Probably.”

  “Probably?” Jon grumbled. “You and the lunch ladies should start a comedy act —”

  “Shh. What’s that?” said Sydney.

  We heard a faint roar from a narrow passage on our left. Cautiously, we stepped in. Soon the roar was all we could hear, echoing all around us. As we walked, the tunnel opened into a cave whose back wall was a rushing waterfall.

  “Buried by sound?” said Jon, quoting the riddle. “Do you think the Crystal Rune is behind the waterfall?”

  “There’s one way to find out.” Sydney nudged my arm. “Owen, the lyre.”

  I was wondering how long it would be before I’d have to use it.

  Ever since we had “borrowed” the ancient Lyre of Orpheus from a museum, and since it turned out that I seemed to know how to pluck melodies from its seven strings, we’d relied on the lyre to do some pretty awesome magical stuff. The fact that playing it almost made my brain explode either meant that I really shouldn’t be playing it, or that was just some kind of weird price you had to pay to get magic to work for you. Either way, the lyre had saved our lives a few times already, so I endured the pain and sucked it up.

  I handed Sydney my torch and took the lyre out of its holster. Holding it close, I plucked first one string, then another. My head instantly began to throb and my eyes felt like fireballs. But the melody was working. In a matter of seconds, the falling water slowed, then thickened like ice, then stopped altogether. It looked like an unmoving curtain with the tunnel continuing beyond it.

  “That still impresses me,” said Jon. “How does the lyre have any magic left, after all it’s been through?”

  It was impressive. The lyre had been through a lot. I’d used it as a weapon. Its strings had been busted more times than I can remember, but it still made music. I hoped that whatever today would bring, the lyre would remain in one piece.

  We quietly approached the frozen curtain, until we heard something in the passage behind us.

  Scuffling.

  Scratching.

  Breathing.

  “So,” Jon whispered. “The mine isn’t abandoned after all.”

  Sydney held up the torch. In its glow we could see a pack of doglike creatures pad slowly into the cave. There must have been a dozen of them. They had no skin — just bones and teeth and skulls and slitty eyes. That glowed.

  “Skeleton dogs,” said Jon, drawing his sword.

  “Killer skeleton dogs,” Dana said softly.

  We had no choice but to run.

  SYDNEY AND DANA HURLED THEIR TORCHES AT THE dogs. We ducked behind the frozen waterfall as I plucked the lyre’s strings in reverse order, releasing the rushing water again.

  Eeeeee! shrieked the skeleton dogs. I had a feeling the water wasn’t going to stop them.

  “Go!” Dana cried. We careened from passage to passage, pursued by the creepy sound of bone feet scraping the floor. Without the torches, we ran in the dark. But the problem with running in the dark is that you hit things. Like each other.

  “Ow!” Jon cried.

  “Get off me!” Sydney yelled.

  “Just follow my voice,” Dana called from up ahead.

  “It’s getting colder,” said Jon. “We’re going deeper into the mines, farther from the surface. Farther from … everything!”

  I didn’t want to think about it. “This way,” I said. I slipped down a side passage and pulled the others with me. It must have tricked the skeleton dogs, because after a while, we couldn’t hear their scary feet pawing the stones anymore. As a matter of fact, we couldn’t hear anything.

  I thumbed the lyre’s highest string gently, and a faint golden light shone out. Now we could see that the passage narrowed and ended a few feet ahead. It led nowhere.

  “I knew it,” Jon groaned. “This is the part where we’re buried by silence. Behold our crypt. The tomb that time forgot. It was nice knowing you guys. Though I could do without our slow and agonizing demise —”

  “Calm down,” said Sydney. “We just have to backtrack.”

  “And meet those dead dogs again?” said Jon. “No, thanks. I’ll wait here.”

  Sydney glared at him. “Wait for what? To starve to death?”

  “Enough!” said Dana. “We’ll think of something.” She opened her copy of Bulfinch’s Mythology and started flipping the pages. Finally, she said, “Owen, feel free to inspire us….”

  Everyone stared at me. “Oh, sure,” I said. “Turn to the kid with the magical lyre.”

  I plucked one string after the other. I pretended I was working on an idea of how to save us. But I didn’t have an idea. I had nothing.

  After a few minutes of string-plucking, I frowned to make it look like I was thinking, and walked the whole length of the passage step-by-step, as if I were measuring. I wasn’t thinking. I wasn’t measuring. I was freaking out.

  “Guys,” I started.

  “What’s that?” Jon interrupted me, pointing up to a small round stone inset in the ceiling. It was polished and black — and unlike anything around it.

  “Exactly what we’re looking for!” I said.

  I held up the lyre and, all at once, the reflection of light from the lyre flashed from the stone directly onto the passage floor. It bounced off at an angle, struck the wall near Sydney’s head, smacked the floor between Jon’s feet, and hit the wall behind Dana, changing color with each new direction. Finally, it came to rest on the wall just over the passage entrance.

  The wall burned brightly for a moment in the whole rainbow of colors, then went clear.

  And there it was.

  A long, slender crystal, set right into the wall.

  Dana gasped. “The Crystal Rune of Asgard! We found it!”

  The rune was small, a kind of sharp-edged, angular oval, with intersecting lines carved deep inside the crystal. It glowed gently with its own white light.

  “Dana, you do the honors,” I said.

  She stood on her toes and slipped the glassy stone from its niche in the wall. “It’s cold. And heavy. My Old Norse is a little rusty, but I think these carvings are a kind of poem. If I can get it right …” She frowned,
moved her lips silently, and then finally read the lines aloud.

  “Whoever holds this crystal key

  Holds close the fate of Odin’s throne.”

  It was a chilling prophecy. When Dana handed the rune to me, I suddenly understood why Loki was all crazy to get his hands on the thing. There was something powerful and electric running through the stone. But the fact that the poem actually foretold the end of the Norse world, the Twilight of the Gods, was why Loki wanted the rune more than anything in the world.

  “Loki knows that the only way for him to survive the Twilight of the Gods is in Odin’s throne,” I said. “With this rune, he can have that. That’s why he wants it so much.”

  “But we have it now,” said Sydney. “And I think we need to get this straight to Odin before anything else —”

  Thud-d-d. Thud-d-d. Footsteps echoed down the passage and into the cave.

  My senses buzzed. “Dogs?” I whispered. I holstered the lyre and drew my sword along with the others. There was silence for a moment. Then came a weird, inhuman shriek. And the rustle of … hooves.

  “Sounds like something bigger than dogs,” whispered Jon. “I knew this was where we’d end our days —”

  “Leave the children be, you nasty goblins!” boomed a voice. “Take that! And that!”

  A flash of metal and the howl of voices filled the air.

  “This way, children!” shouted the booming voice. Suddenly, there was a man standing at the mouth of the passage. In one hand he held a broadsword; in the other, a torch sizzling with red flames. He was huge, with long blond hair, a big beard, and a smile.

  “You’d better come with me,” the man said when we didn’t budge. “These rock goblins are hungry!”

  A small army of green-skinned creatures swarmed out from the rocks. They were as skinny as stick figures, with tight green skin, curving talons, and hoofed feet. I resisted the sudden urge to throw up.

  The man swung his blade sharply, and two goblins jumped away screaming. The pack started pelting him with rocks and daggers, but nearly everything bounced off the man’s arms and legs as if he were made of iron.
