Debriefing the Dead (Book One of The Dead Series) - The Dead Series, #1

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 deal: 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?
