The Somerset Tsunami: ''The Queen of Historical Fiction at her finest.'' Guardian

A sinking boat.
A girl in disguise.
A disappearing sea.

When Fortune Sharpe carves a boat from a tree with her beloved brother, Gem, she's only having a bit of fun. But now is not the time for a girl to be drawing attention to herself. She is sent away to find work dressed as a boy. Luckily a rich manor house is hiring.

Yet Berrow Hall's inhabitants harbour dangerous secrets of their own, the suspicious owner is hunting for witches, and the house itself is a little too close to the sea.
