DWZ – The Globe & Mail
"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."
