The girl of hawthorn and glass
(Book)

Even teenage assassins have dreams. Eli isn't just a teenage girl -- she's a made-thing the witches created to hunt down ghosts in the human world. Trained to kill with her seven living blades, Eli is a flawless machine, a deadly assassin. But when an assignment goes wrong, Eli starts to question everything she was taught about both worlds, the Coven, and her tyrannical witch-mother. Terrified that she'll be unmade for her mistake, Eli seeks refuge with a group of human and witch renegades. To earn her place, she must prove herself by capturing the Heart of the Coven. With the help of two humans, one motorcycle, and a girl who smells like the sea, Eli is going to get answers -- and earn her freedom.
