Fledgling by Octavia E. Butler
Fledgling tells the story of a 53-year-old woman who was genetically modified to be a vampire. That's right, she was turned in a laboratory not through the "normal" means of being bitten by another vampire. She tells her tale of trying to adapt to her new body, while at the same time trying to piece together elements of her former life. And let's just say that the road to redemption is a bloody one.
