The Sunlight Slayings: Oliver Nocturne, Book 2

When a vampire's best friends are a human and a zombie, he's bound to feel like a freak
Two months after Dean's death, Oliver is a hero in the vampire world. But even though he wasn't responsible, he's having trouble sleeping and has never felt more alone.  
 
Surprisingly, Dean returns—as a zombie, no less—and though Oliver is glad to have his friend back, they need to hurry; someone has been slaying vampire children, and all the evidence points to Emalie. Can Oliver and Dean find her before the vampires do? Their search takes them deep into the underground black market and high into the Seattle night. As they discover the powerful forces behind the sunlight slayings, Oliver finds that it's all intricately tied to a future he doesn't want.
