Shape of Night - Tess Gerritsen

If the walls could talk . . . they'd tell her to leave. Now. When Ava arrives at Brodie's Watch, she thinks she has found the perfect place to hide from her past. Something terrible happened, something she is deeply ashamed of, and all she wants is to forget. But the old house on the hill both welcomes and repels her and Ava quickly begins to suspect she is not alone. Either that or she is losing her mind. The house is full of secrets, but is the creeping sense of danger coming from within its walls, or from somewhere else entirely?
