Night Huntress follows Catherine 'Cat' Crawfield, a half-vampire raised by a bitter mother to believe that all vampires are monsters. By night she hunts them, luring them in with her looks and staking them before they can feed. Everything changes when she is overpowered by Bones, a centuries-old British vampire bounty hunter who recognizes her unique abilities and offers her a deal: train with him to become an elite monster hunter, and he'll help her find her vampire father. What begins as a partnership of necessity becomes something neither of them can deny or escape.

Cat Crawfield is a fiercely independent, smart-mouthed, deeply principled heroine whose half-vampire status makes her an outsider in both the human and undead worlds. Her arc from grudging warrior to devoted partner—while never losing her edge or her humor—is what keeps readers returning across ten volumes. Bones, the charming British vampire at her side, matches her in intelligence and passion, and his centuries of experience never make him condescending, only devoted.

Across ten books, Cat and Bones face escalating supernatural threats—rogue vampire networks, ghoul queens, zealot-fueled species wars, and government conspiracies—while navigating the challenges of a relationship between a half-mortal and an immortal. The series expands to explore the broader vampire world, introduces a rich ensemble of allies and enemies, and ultimately delivers a dual-perspective retelling that deepens the origin story from Bones' point of view. Themes of identity, belonging, the meaning of humanity, and the courage it takes to trust love completely run throughout.
