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.
