Crap, there's just too many of them.
I Like most of the Parker series, but I'm especially fond of "REPLACEMENT VALUE", "KEEPER", and "BLACKOUT".
I could go on for days about how Faibhar's "THE TARGET" gives me powerful erections....
Terry Madison's stuff. Then one about the wedding, where the sister is tortured until the bride agrees? And "COLD".
Kallie... Thomas, is it? The PDF's have no credit for the author... "PUPPY LOVE", "COLDWOOD", "THE PERFECT GIRL"... "THE DIG" is quickly becoming a favorite, despite how dark and unhappy the ending is.
My all time favorite is one I can't find, but I'd SWEAR I got it from this forum. It was about three latinos who capture and rape a blond girl named Jenny in a stolen van and bring her with them to Mexico, where she is raped repeatedly and Dommed by the uncle of one of the three guys. I remember calling it Border Nightmare, but I have no idea who wrote it or what the orginal title was...
