This is a well-told novel of obsession between two twins caught in an innocent, incestous, homosexual relationship that becomes ruinious. The interesting thing about this novel is that it sticks with you after reading it. In case you don't know, it was turned into the film, Dead Ringers, which featured Jeremy Irons. Dead Ringers has an entirely different focus than the novel, for obvious reasons, but the film is as equally successful. Both the novel and the film should be checked-out by horror fans; both are unjustifiably forgotten and overlooked. I'm not sure if three or four stars is the right rating, but it's a good book, regardless; try to find it at your library or used book store, and read it. It's one of the better horror novels I've ever read, although a different type of horror is explored.
