She's Not There — P.J. Parrish

They say it's better to battle the devil you know. But what if you don't recognize him before it's too late?

She knows her name is Amelia, but after waking up in a hospital battered and bruised with just the clothes on her back, it's all she knows. Unable to piece together her shattered memory, she's haunted by a vision: menacing faces and voices implying her nightmare is far from over.

Relying only on her wits and her will to live, Amelia becomes a fugitive from a mysterious man, and a life she can't even remember. But the past she's fleeing has no intention of letting her go.
