The Girl Who Fell - Violet Grace

Chess Raven is a hacker who has grown up with nothing and no one. Her parents died when she was three and her foster care situation turned out badly - very badly. But on her sixteenth birthday, her life is turned upside down.

Chess learns her mother was Queen of the Fae and her father was a brilliant physicist. The unique blend of her mother's fairy blood and her father's humanity gives Chess - and Chess alone - the ability to unlock a mysterious vessel that will unleash unimagined powers - with devastating consequences. Thrown into a new world where nothing is at it seems, Chess must work out who to trust as vying forces race to control her. Or kill her.
Reunited with her childhood friend Tom Williams, an enigmatic shape-shifting unicorn, Chess discovers love for the first time and is prepared to risk her life for it. But first she must learn to overcome a fear of her own power and stop waiting for other people to save her. She is the one she's been waiting for.
