Soul Ties — Lisa Swallow

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. She must hunt down Keir since she needs his Nephilim soul to trade for her freedom. When she arrives on campus and meets Keir, she also meets a strange girl, Dahlia, who has an inexplicable hold on him. Unexpectedly Ava discovers Keir holds secrets that are more valuable than his Nephilim soul â€" secrets she could trade for the life she wants. When she uncovers the true fate of the souls she takes back to her superiors, Ava's world is turned upside down. She finds herself in the middle of a war where the lines between good and evil are blurred and she only has two choices… Betray Keir and live or join his battle and risk going to hell.
