Black Wings, Gray Skies (Black Hat Bureau Book 4) by Hailey Edwards

Black Hat Bureau, Book 4

Monsters with a taste for children are nothing new, but fairy tales never mentioned this nightmarish predator. Rue has her hands full tracking the creature hunting the streets of Charleston, but a call from home divides her attention—and her loyalties.

A stranger has come to Hollis Apothecary, asking questions that prickle the hairs on her nape, but she can’t abandon the victims based only on a bad feeling. The pit in her stomach only grows when the stranger takes a hostage and makes his demands. He wants to talk to Rue, face to face. Or else. What he has to say will change her life, and her perception of her past, forever.
