"This compelling novel explores the relationship between two brothers who are opposites… Once you're hooked you won't be able to put it down until the end."
– Voice of Youth Advocates
Read More"A chilling sci-fi novel…. Tension mounts and the drama plays out to a grand conclusion."
– The Horn Book
Read More"Weaving thematic threads of sibling rivalry and affection, a Faustian motif, high adventure, and of course, the power of true love, Oppel's prose rarely falters, despite his occasional flirtation with melodrama. The dialogue is swift and rings true. Some of the characters would fit perfectly into a Dickensian underworld and the cumulative effect of all these riches is a novel of striking impact."
– The Globe & Mail
Read More"Oppel has crafted a superior science-fiction novel set in the near future… Everything about this novel is believable: the characters and their motivations, the development of their relationships, even the non-Hollywood conclusion. Readers are left with satisfaction that the mystery has been solved, but are not placated with a hurry-up happy ending. An excellent bridge to the works of Ray Bradbury and Frank Herbert."
