I looked up my long TBR list, and I've had Joyce Carol Oates' THE GRAVEDIGGER'S DAUGHTER on it for a long time. I think it's the length of the book that put me off - 582 pages.
It does sound interesting, but dark. Publisher's Weekly starred review said, " At the beginning of Oates's 36th novel, Rebecca Schwart is mistaken by a seemingly harmless man for another woman, Hazel Jones, on a footpath in 1959 Chatauqua Falls, N.Y. Five hundred pages later (which includes a backstory of her life), Rebecca will find out that the man who accosted her is a serial killer, and Oates will have exercised, in a manner very difficult to forget, two of her recurring themes: the provisionality of identity and the awful suddenness of male violence."
