Awakening : Kelley Armstrong

You don't have to be alive to be awakened.

Chloe Saunders is a living science experiment—not only can she see ghosts, but she was genetically altered by a sinister organization called the Edison Group. She's a teenage necromancer whose powers are out of control, which means she can raise the dead without even trying. Now Chloe's running for her life with three of her supernatural friends—a charming sorcerer, a cynical werewolf, and a disgruntled witch—and they have to find someone who can help them before the Edison Group catches them.

Or die trying.
