On an English university campus, Ava is hunting Keir. She needs his Nephilim soul to trade for her freedom. But Ava didn't expect to find terrible secrets about the fate of the souls she takes. Or fall in love. Soul-hunter Ava has retrieved hundreds of souls from demons but has never been assigned the dangerous mission for a Nephilim soul. When she arrives on campus and meets Keir, she discovers he has secrets more valuable than his Nephilim soul - secrets she could trade for the life she wants. She also meets Dahlia, the human girl with an inexplicable hold over Keir, and secrets of her own. When she uncovers the true fate of the souls she takes back to her superiors, and what Keir is doing to try and prevent it, Ava’s world is turned upside down. Forced into a battle where the lines between good and evil are blurred, Ava is faced with the choice between saving herself by betraying those around her, or helping Keir and risking her life. Ava’s ultimate choice: retrieve Keir’s soul and live, or join his battle and risk going to Hell. Warning: This book contains graphic language.
