Praise for The Percy Jackson Series by Rick Riordan:

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

Praise for The Kane Chronicles by Rick Riordan:

The Red Pyramid
★ “The first volume in the Kane Chronicles, this fantasy adventure delivers what fans

loved about the Percy Jackson and the Olympians series: young protagonists with
previously unsuspected magical powers, a riveting story marked by headlong adventure, a

complex background rooted in ancient mythology, and wry, witty twenty-first-century
narration.”

—ALA Booklist (starred review)

“Riordan fans young and old will eat this new book up.”

—The New York Times Book Review

“Fans of the Riordan magic—equal parts danger, myth, and irreverence—will embrace
this new series with open arms.”

—Horn Book

“This tale explodes into action from chapter one.…Readers pining for Percy Jackson will
find new heroes in Carter and Sadie Kane.”

—Kirkus Reviews

“Once again, Riordan masterfully meshes modern life with mythology and history,
reinvigorating dusty artifacts such as the Rosetta stone and revitalizing ancient Egyptian

story lines.”

—The Los Angeles Times
★ “A truly original take on Egyptian mythology…A must-have book.”

—School Library Journal (starred review)

The Throne of Fire

★ “…Riordan kickstarts the action, never lets up on the gas, balances laughs and losses
with a sure hand, and expertly sets up the coming climactic struggle without (thankfully)
ending on a cliff-hanger. It’s a grand ride so far, showing nary a sign of slowing down.”

—School Library Journal (starred review)

“As in his earlier novels for children, Riordan combines hard-hitting action scenes,
powerful magic, and comic relief with the internal waves of love, jealousy, and self-doubt
that make his young heroes so very human. Lit by flashes of humor, this fantasy adventure

is an engaging addition to the Kane Chronicles series.”

—Booklist

Praise for The Heroes of Olympus Book One: The Lost Hero
by Rick Riordan:

“Riordan’s storytelling is as polished as ever, brimming with wit, action, and heart—his
devotees won’t be disappointed.”

—Publishers Weekly

“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 everything they’ve been pining for.”

—Horn Book
