I've read a few, but sadly I wish I could remember their titles. One was a novel about some guys kidnapping a well-known celebrity, well, a fictional celebrity, and holding her for a ransom. One of the kidnappers rapes her and it was very well-written and graphic.
Another book I recall was about a serial rapist going around abducting college girls and raping them in his car. One particular scene that really turned me on was the guy sitting in a parking lot at a beach and watching some girls play beach volleyball. There is one Hispanic girl he has his eyes set on. The author goes into great detail describing her and talking about how worked up the rapist is becoming as he watches her. The author doesn't tell us how he abducts her, but then we move to a scene where she is in the backseat of the guy's car and he is raping her. An interesting thing was that during the rape, the rapist would be having flashbacks about other rapes he committed.
