Books in the Deluge series

Some secrets are worth killing for.The ancient city of Kepos sits in an isolated valley, cut off from the outside world by a towering wall. Behind it, the souls of the dead clamour for release. Or so the priesthood says.Kala has never had any reason to doubt their word - until her father dies in suspicious circumstances that implicate the city's high priest. She's determined to investigate, but she has a more immediate problem: the laws of the city require her mother to remarry straight away.Kala's new stepfather is a monster, but his son Leon is something altogether more dangerous: kind.With her family fractured and the investigation putting her life in danger, the last thing Kala needs is romance. She would rather ignore Leon entirely, however difficult he makes it. But when she learns the truth of what really clamours behind the wall at the end of the valley, she faces a choice: share what she knows and jeopardise her escape, or abandon him to his fate along with the rest of the city.If she doesn't move fast, then no one will make it out of the valley alive.
