The stranger, the better.

I love books that have strange plot twists also. My favorites series right now would be Jacqueline Carey's Kushiel's Trilogy. Heres a twist for you: Born into houses of pleasure, sold into identured, taught to spy, hand maiden of a cruel god, and becomes near cousins to the queen of the releam. Ohh thats the basics, there's much more to this heroines story. But you have to read in order to find out. The triology starts with Kushiels Dart. Mind you starts of with the back story on the main character and then takes off.

Try reading this strange book-The Man Who Mistook His Wife for a Hat!

Have you ever read any Jeffery Deaver novels? He wrote the Bone Collector which was made into a movie with Denzel Washington and Angelina Jolie. He's written around 20 thrillers and pretty much all of them have crazy unexpected twists.

Shadow of the Wind is good. It's got twists. No vampires, but it's got burned men and arson.
