After barely surviving a plot to destroy her school and its menagerie of alien patients, could things get worse for novice exoveterinarian Zenn Scarlett? Yes, they could: her absent father has been kidnapped.
Desperate to find him, Zenn stows away aboard the "Helen of Troy, " a starliner powered by one of the immense, dimension-jumping beasts known as Indra. With her is Liam Tucker, a Martian boy who is either very fond of her, very dangerous to her, or both. On the verge of learning the truth about her missing dad, Zenn's quest suddenly catapults her and Liam thousands of light years beyond known space, and into the dark heart of a monstrous conspiracy.
