Books in the Dead series

Sometimes the only way to stop the world from going to Hell is by working with Demons. Hyacinth Finch has one goal: Save her nephew Geordi from the Hell Demon who kidnapped him. But to succeed, she'll have to work with his demon Mafia relatives, which she swore she'd never do. Worse, she'll have to make another deal with the High Demons who murdered her. But Geordi's life is worth it, even if she loses her own humanity in the process. Meanwhile, Hyacinth's ghost boyfriend Eric is wasting away, after being ejected from his "borrowed" body. While digging in his past for something to make him fight for survival, she uncovers secrets that could destroy their relationship. Moreover, her feelings for Geordi's demon cousin Jason are stronger than ever, though every morally impossible choice she makes drives him farther away. Can she save Eric and Geordi, without losing herself-and Jason-forever?
