Gaby Winters' life used to be pretty normal. She lived with her best friend. She worked in a library. She was slowly getting over the death of her twin brother, Jude. And then Rafa came looking for her.

     With him, her blood-soaked nightmares stopped. But now they are reality. She is one of the Rephaim - a wingless half angel, descended from the Fallen. Demons exist and they are hunting her.

     She knows she's alive when she's meant to be dead. And that means maybe Jude is too. So why isn't she out there looking for him?
