Bat Blood - Part Two - Richard I Myerscough - Bog

Claraicy had been both physically and psychologically abused by her father. While abandoned in the woods and left to die, she was attacked by a pair of strange creatures. After surviving through a harsh winter, she begins to mutate and grow stronger.
Unable to think like a rational human being, she lashes out. The police, army and several others get involved, each with their own motives and agendas. She is hunted down for both what she knows and the mutated cells inside her.
Unable to control her, Duncan, the soldier responsible for capturing her, gets desperate. While unleashing all the military resourses at his disposal, the body count increases. As his mind turns darker, so do his methods.
As Claraicy turns more creature than human, she feels like she has been given a new and better life. Her only problem is, she can't get over her bitter hatred for Santa Claus.
