Isabella 'Izzy' Sage has spent her life working toward one goal: returning to Belle Isle, Detroit, to become keeper of the death gate where her parents were mysteriously killed. Raised by her grandfather among the Bruja of New Orleans, she carries magic she has kept carefully hidden. On her first day on the job, an enhanced wraith crosses through the gate and begins murdering people, drawing the boisterous, powerful Grimlock reaper family into her territory whether she wants their help or not.

Izzy Sage is sharp-tongued, fiercely independent, and deeply loyal, hiding the full extent of her bruja powers while she hunts for the truth about her past. Her sarcasm is her armor, but her genuine care for the people around her — including the loud, maddening Grimlocks — keeps breaking through.

Across nine books, Izzy unravels the dark secrets behind her parents' deaths while falling reluctantly in love with the irreverent Braden Grimlock. The series escalates from a local wraith problem to a full revenant war threatening all of Detroit, culminating in a showdown with the ancient god Pan himself. Throughout, the Grimlock family's found-family chaos provides equal parts humor and heart.
