Lily's emotional problems run deep seven miles deep. After she gets kicked out of school for her destructive behaviour, Lily agrees to an unusual fresh start: going with her scientist mum to live at Deephaven, an experimental deep-sea mining rig and research station located at the bottom of the ocean. Lily instantly regrets her decision: claustrophobic and isolated, it's hardly her idea of home. Turns out, Deephaven has problems of its own. The head scientist, they quickly learn, has disappeared just as he was on the brink of a shocking discovery. In the darkness of the deep, something is stirring ... something dangerous. And it's calling out to Lily.

A mind-expanding thriller set in the ocean's depths, a terrifying struggle for survival and the story of one girl's path to self-acceptance.
