PRAISE FOR RICK RIORDAN
Percy Jackson and the Olympians
The Lightning Thief
“Perfectly paced, with electrifying moments chasing each other like heartbeats.”
—The New York Times Book Review
The Sea of Monsters
★ “In a feat worthy of his heroic subjects, Riordan crafts a sequel stronger than his compelling debut.”
—Publishers Weekly (starred review)
The Titan’s Curse
“All in all, a winner of Olympic proportions.”
—School Library Journal
The Battle of the Labyrinth
★ “Look no further for the next Harry Potter; meet Percy Jackson, as legions of fans already have.”
—Kirkus Reviews (starred review)
The Last Olympian
“The hordes of young readers who have devoured Rick Riordan’s books…will no doubt gulp down this concluding volume as greedily as they would a plateful of ambrosia, or maybe pizza.”
—The Wall Street Journal
The Heroes of Olympus
Book One: The Lost Hero
“Percy Jackson fans can rest easy: this first book in Riordan’s Heroes of Olympus spin-off series is a fast-paced adventure with enough familiar elements to immediately hook those eager to revisit his modern world of mythological mayhem. Rotating among his three protagonists, Riordan’s storytelling is as polished as ever, brimming with wit, action, and heart—his devotees won’t be disappointed.”
—Publishers Weekly
“With appealing new characters within a familiar framework, this spin-off will satisfy the demand for more.”
—Booklist
“Riordan excels at clever plot devices and at creating an urgent sense of cliff-hanging danger. His interjection of humor by incongruous juxtaposition…provides some welcome relief. The young heroes deal with issues familiar to teens today: Who am I? Can I live up to the expectations of others? Having read the first series is helpful but not essential, and the complex plot is made for sequels.”
—School Library Journal
“Riordan extends the franchise in a logical direction while maximizing the elements that made the first series so popular: irreverent heroes, plenty of tension-filled moments fighting monsters, and authentic classical mythology mixed in with modern life. Completely in control of pacing and tone, he balances a faultless comic banter against deeper notes that reveal the characters’ vulnerabilities. With Percy Jackson slated to make an appearance in later volumes, fans nostalgic for the old books should find in this new series
