The Infinite Life of Emily Crane — Jaron Lee Knuth

Emily Crane doesn't want to die, but what she's been doing for the past seventeen years can't really be called “living,” so when a tragic event cuts her teenage life short, she feels nothing for the loss. But when she awakens only hours later, very much alive and without a single injury on her body, she is thrust into an existence that she never thought possible. Confronted with government scientists, beautiful assassins, and secrets that may threaten every mortal on the planet, Emily's new life is suddenly more exciting, more dangerous, and more meaningful than she could have ever imagined.When Emily Crane dies, her life finally begins.
