ALA Booklist

Readers longing for a return to Camp Half-Blood will get their wish in the first novel of the Heroes of Olympus series, which follows Riordan's popular Percy Jackson and the Olympians series and includes some of the same characters in minor roles. The new cast features Jason, Piper, and Leo, teen demigods who are just coming to understand and use their unique abilities as they learn how much depends upon their wits, courage, and fast-developing friendship. Setting up the books to come, the backstory of a master plan to unseat the gods is complex but is doled out in manageable bits with a general air of foreboding. Meanwhile, the action scenes come frequently as the three heroic teens fight monstrous enemies in North American locales, including the Grand Canyon, Quebec City, Detroit, Chicago, Omaha, Pikes Peak, and Sonoma Valley. Flashes of humor lighten the mood at times, but a tone of urgency and imminent danger seems as integral to this series as the last. With appealing new characters within a familiar framework, this spin-off will satisfy the demand for more.

Horn Book

Camp Half-Blood has three new arrivals: Piper, daughter of Aphrodite; Leo, son of Hephaestus; and Jason, son of Zeus. With the Titan war over, a new threat has emerged: a prophesied clash with Gaea's youngest children, the giants, who are returning to overthrow the Olympians. As with his Percy Jackson series, Riordan is completely in control of pacing and tone.

Gr 5-9 This book will delight fans of The Lightning Thief (Hyperion, 2005) as Percy, Annabeth, and others play roles in the new prophecy and its subsequent quest. A few months after The Last Olympian (Hyperion, 2009) ends, Jason wakes up on a bus filled with problem kids from the Wilderness School who are headed to the Grand Canyon. He has no memory of his previous life, but seems to be with his girlfriend, Piper, and his best friend, Leo. The action takes off quickly: storm spirits attack them and capture their coach, who turns out to be a Satyr. Searching for Percy, who is missing, Annabeth arrives and takes the three to Camp Half-Blood, where they learn that they are demigods. Their parents are gods in their Roman rather than Greek personae. By sunset of the solstice in three days, the teens must rescue Hera, Queen of the gods, or Porphyrion, the giant king created to destroy Zeus and unseat the gods of Olympus, will rise. Their quest takes them across the United States, sometimes flying on a mechanical, 60-foot dragon, as they use their power and wits against Medea, King Midas, and the giant cannibal Enceladus. Riordan excels at clever plot devices and at creating an urgent sense of cliff-hanging danger. His interjection of humor by incongruous juxtapositionMedea, for example, heads up a New York City department storeprovides 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.— Connie Tyrrell Burns, Mahoney Middle School, South Portland, ME
