The only thing Hyacinth wants is her life back. Literally. She and her sister were murdered by demons, leaving her young nephew Geordi to his father’s family in the brutal Sicilian Mob. Then Archangel Michael offers her a recapture a powerful rock the demons stole, and she can live long enough to find Geordi a safe home. Refuse, and she’ll continue up (or down) to the Afterlife. So, slightly more alive than dead, she heads for Turkey and the Demons, taking Geordi, her mysterious neighbor Jason, and a sexy dead guy only she can see with her. But the hardest part won’t be battling Demons, meeting Satan, or dodging Middle Eastern customs—it will be later, when Geordi is settled, and Michael rips her away again. How can she abandon her nephew? Or can she outwit the Angel of Death himself, and stay with Geordi forever?

Hyacinth always assumed dying would simplify her life. But when her new boss, Archangel Michael, sends her on her first official mission—to retrieve a powerful rock from a collector in Germany—things go downhill fast. For one thing, the Dead keep popping up, expecting her to guide them to the Afterlife. For another, her part-demon nephew Geordi's powers are starting to leak out, at age seven. What if Michael finds out about him? Worse, what if Satan does? Then there's her love life-after-death. Rooming with a dead French cop no one else can see is complicated enough. But when Jason, Geordi's lying Dioguardi Demon cousin, resurrects himself—so to speak—all Hell breaks loose. Literally. Can Hyacinth get Michael's rock back before Satan steals its powers and breaks free of his prison? Or will her single-minded pursuit put those she loves—and the rest of the world—in the path of Satan's fury?

Hyacinth Finch’s life-after-death just got more complicated. High on her to-do list: Stop Satan from stealing any more of Archangel Michael’s powerful relics, marshal her Dead Army of two thousand souls, and recapture dozens of escaped Hell Demons, to prevent six thousand dead Nazis from wreaking havoc in the world. And on top of all that, her onetime ghost boyfriend has hijacked the body of a former German militant, which has its ups and downs for their relationship. Then, just when things seem to be under control, her nephew Geordi’s powers start leaking out, and Hyacinth’s own begin to change. She must discover where their abilities originated. But as she digs deeper, will the truths she uncovers do more harm than good? And more importantly—can she figure it out, before Satan escapes from Hell and takes Geordi for himself?

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?
