Blood drive
(Book)

Anna Strong is a vampire caught between two worlds. She clings to what makes her human--her family, her job, her lover. But the pull of the undead is a siren song becoming impossible to resist. Then she discovers her brother, who was tragically killed fourteen years ago, had a daughter he never knew about, and Trish is a child caught up in the worst kind of human nightmare. To save Trish, Anna may have to surrender to the animal side of her nature. As Anna stalks Trish's predators, the concepts of good and evil are no longer clearly defined. Now Anna must determine who is the real monster--the humans who prey on children or herself, the vampire trying to save them.
