The Girl Who Broke the Sea By A Connors

After she gets kicked out of school for her destructive behaviour, Lily agrees to an unusual fresh start: going with her 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.
