"Rick Riordan's new series is simply brilliant--maybe his best yet! I thought I knew Norse mythology, but now that I've read the gripping and hilarious Sword of Summer, I'll never see Thor the same way again. Get ready to stay up all night reading!"--New York Times #1 best-selling author Harlan Coben

"Perfectly paced, with electrifying moments chasing each other like heartbeats."--New York Times Book Review

* "In a feat worthy of his heroic subjects, Riordan crafts a sequel stronger than his compelling debut."
--Publishers Weekly (starred review)

"All in all, a winner of Olympic proportions."--School Library Journal

"The clash of modern and classical worlds is both exciting and entertaining."--The New York Times Book Review

"The novel's winning combination of high-voltage adventure and crackling wit is balanced with scenes in which human needs, fears, and ethical choices take center stage."--Booklist (starred review)

*"The wit, rousing swordplay and breakneck pace will once again keep kids hooked."--Publishers Weekly (starred review)

"Adventure fans will relish the action as their heroes confront formidable foes, while readers who have come to love the characters will enjoy following the different individuals as they take the stage in scenes that are usually dramatic, often witty, and occasionally surprising. A satisfying, penultimate entry in the Heroes of Olympus series." --Booklist Online

"In this adventure, victories are hard-won and the essence of bravery nuanced, making the journey as satisfying as it is entertaining."--Kirkus Reviews

"Riordan masterfully orchestrates the huge cast of characters and manages a coherent, powerful tale at once exciting, philosophical and tear-jerking. The bestselling series' legions of fans will cheer their heroes on and rejoice in such a compelling conclusion to the saga."--Kirkus Reviews (starred review)

"With a true storyteller's sense of pacing, Riordan creates another compelling adventure, right down to the cliff-hanger at the end. Stay tuned for volume four."--Booklist

"With his now-trademark zero-to-60 acceleration, the author engineers a ghostly possession to set Greeks and Romans at odds and initiates the Prophecy of the Seven, hurtling Annabeth, Percy, Piper, Leo, Hazel, Frank and Jason into a pell-mell flight on the magical trireme Argo II. Here, Riordan's infectious love for his subject matter really comes through, even as he takes some real risks with his characters. A literal cliffhanger leaves eager readers hanging; next stop: Greece--and Tartarus."--Kirkus Reviews

"Should pacing and wit continue unabated into the third volume, whose foretold European setting promises further freshness, fans will eagerly await numbers four and five."--Kirkus Reviews

"The Sword of Summer is a propulsive, kinetic, witty rebooting of Norse mythology with all the charm of the Percy Jackson novels. Instantly likeable heroes! Insane action! Cool villains! A twisting, turning, always exciting story! Rick Riordan does it again, even better."--New York Times best-selling author Michael Grant
