I wouldn't recommend this if you are looking for an actual romance. The novelist is a manipulative bastard and the editor lets him get away with far too much. It's very interesting from a psychological standpoint though. (and, you know, sexy times)
edit: WOW AND I THOUGHT THE FIRST STORY WAS WIERD. all of these are very... dysfunctional relationships. They all have happy endings (as far as that goes) but uh... just make sure to read the tags first, okay?
