Life as a vampire isn't so easy. Especially for Ava Sumner who is different from her new vampire family. She sees things differently. She has a harder time connecting with William, her blood bond. She has natural instincts that take most vampires months to master. Not to mention, she's descended from a long line of Hunters, beings who are thought to be immune to the bite of a vampire. There's a name for what Ava is now, something so rare and mysterious: Unnatural.
