Deep Water by T. W. Iain

Rodin’s old life is over. But before he can move on, he needs to understand his past. He needs to know how he escaped death in the bunker, and why he threw himself into the chasm. And he needs to know why others still want him dead.
After a decade separated from society, Paskia’s life is finally back on course. But Correction has not worked, and she is still considered a threat. If Paskia is to survive, she must once again confront the secrets she buried all those years ago.
As Rodin and Paskia seek answers, Authority seeks closure. It doesn’t like loose ends.
Problems must be removed. Permanently.
