And Falling, Fly by Skyler White

 Dark dark dark. Those beings that we call vampires are fallen angels, who subsist on the blood and emotions of their victims, Olivia, the Angel of Desire, believes that the only way she can be restored to her former, unfallen, state is if a human actually loves her for herself, rather than being merely infatuated and "in lust" with her. Other vamps seem to revel in their fallen state, and have no need for redemption.

Dominic O'Shaugnessy is a brain chemistry researcher in California who may or may not be victim of a curse which forces him to be reincarnated endlessly, with full "flashback" memories of all of the wives and children he has had to bury over the centuries. The team for which he works is trying to find a way to biochemically remove specific memories for trauma victims, and he has a vested interest in the success of the project, so when a wealthy benefactor is willing to give him millions for his research so that he can remove the "false memories" leading to her goddaughter's obsession with vampirism, he leaps at the chance.

White's prose is at times evocative, novel and creative.

"-but Adam's end-of-day reunion ritual dictates that we confess our grievances using the form of the employee's creed... I elect to berate The Client, the mysterious entity who pays our salaries and thus, in a market economy, is our superior and therefore, in American mythology, our inferior. Adam recites his day in the Idiot Boss variation..."

But....I just didn't quite frankly give a hoot about what happened to anyone in this book.

If you like it dark and twisted, give Skyler White a try.
