Afraid of the Dark — Donna Anders

As a single mother struggling to get by in a tough neighborhood, policewoman Jessie Cline knows she can't protect her son from the streets forever. For his sake, she takes a job as assistant police chief in a small island town off the coast of Washington state where she lived as a child. But her search for a safe haven will lead her toward more danger than she ever imagined.

Even as Jessie tries to start anew, the secrets of her family's painful past -- and her own troubled life -- return to haunt her and threaten her son. Someone on the island knows Jessie very well, and will do anything to drive her away. They will stalk her. They will frighten her.

And if she cannot unravel a sinister disappearance that connects her past to the present, they will kill her...
