In this thought-provoking sequel to The Rule of Claw (Carolrhoda, spring 2009), author John Brindley continues to explore a future world where genetic experiments have accelerated the process of evolution. Phoenix is an earthbound Agle, one of several genetic variations on humans. She believes she is deformed because she cant fly. She is in love with the image of perfection, the air Agle Gabriel. What will she risk to be with him? The stakes are high: a delicate balance has been formed between the Rodents, Raptors, and Agles in the rebuilt city. Is Phoenix willing to jeopardize their safety? What chance does she have when the Adults, a violent and fanatical human offshoot, return, claiming civilization for themselves once and for all?
