Gang-related murders cast a dark shadow over the city as a new player emerges in the deadly fentanyl trade. Maude Kaminski, technical analyst for the Chicago PD, takes her place on the task force created to end the bloody territory wars.

But Maude's world is upended when a child's backpack is discovered among the possessions of a dead homeless woman. The backpack belonged to Maude's 2-year-old brother, Michael, and is the first trace of him since he was taken -- since Maude let someone take him -- over twenty years ago.

As Maude desperately searches for other signs of Michael she turns for help to her best friend, chef Sags Pfister, who harbors a dark past of her own. Long-buried secrets begin to surface, forcing Maude from behind her computer into undercover work and underneath the dark streets of Chicago, where she has to confront her deepest fears. How far would she go to protect her family?

For fans of Janet Evanovich, readers will love this witty, tense, rollercoaster of a ride!
