"Didn't you hear the rumors before coming here?"

The Great War has just ended and Spanish Flu is decimating the population. Ravenswood Hall remains isolated from the world, poised at the top of a hill on an island off the rocky coast of Maine.

It is to this house that Emmaline West has traveled, bent on revenge. She has been left lame from polio, lost her home and her family, and one man is to blame—Garrick Coleridge, her dead sister's fiancé. But instead of the heartless monster she is set on killing, she finds a man tormented by a secret that he risked his life on the battlefield to escape.

The pandemic worsens on the mainland, trapping Emmaline on the island. When a member of the household is murdered, suspicion falls on her. Plunged into the shadowy lives of the Coleridge clan, Emmaline is forced to seek Garrick's help to clear her name.

But this murder is only the beginning. Like peeling back the layers of an onion, the secrets of Ravenswood Hall are revealed and no one is safe. Is it one killer or several? Emmaline and Garrick enter into an uneasy alliance to find out - and to stay alive.
