Zenn Scarlett's novice year of exoveterinarian training on Mars isn't quite going to plan...

After facing a plot to destroy her school and its menagerie of alien patients, could things get worse? 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 father, Zenn's quest suddenly catapults her and Liam thousands of light years beyond known space, and into the dark heart of a monstrous conspiracy.

Braving a gauntlet of lethal environments and unearthly life forms, Zenn's courage is tested as never before. With the fate of entire worlds in the balance, she is racing headlong into trouble... again.
