In a world where the supernatural coexist with humans, Rachel Morgan is a witch and bounty hunter extraordinaire in Cincinnati's murky underbelly known as the Hollows. A place swarming with creatures that thrive in the shadows. Having quit her job at the Inderland Runner Services, Rachel finds herself a target for assassination. With an I.S. death warrant hanging over her, she forms an uneasy alliance with Ivy, a living vampire, to clear her name. Together they must navigate through treachery, power plays, and dark magic, where distinguishing ally from enemy is anything but simple. It's a realm where the norms of society are flipped, and survival demands a blend of strength, wit, and the occasional partnership with beings on the edge of humanity.
