Magic Blood: The Warlock Books in Order

Magic Blood: The Warlock is a collaborative urban-fantasy series by Katerina Martinez and Tansey Morgan. It follows Hailey, a librarian who wants a normal life but gets pulled back toward the supernatural dangers she thought she had left behind.

Normal does not last long around demons.

The story begins with Demons and Deception, when a strange encounter at the library leads Hailey into a new problem involving demonic creatures, missing answers, and people who know more about her past than she does. Levi becomes part of that changing world, and their interactions add romantic tension to a mystery that keeps widening.

The sequence continues with Mages and Masquerades, Scions and Sorcery, Hellfire and Homicide, and Warlocks and Wickedness. The titles reflect the series' mix of magical investigation and escalating paranormal threats. Each book pushes Hailey further into a world where her old skills and hidden connections matter more than she expected.

The setting has a lively modern urban-fantasy feel. Demons, mages, magical objects, and supernatural factions exist alongside the everyday work of keeping a library open and pretending life is under control. Hailey's point of view keeps the danger personal, because she is not seeking power for its own sake. She is trying to understand why trouble keeps finding her.

Expect a continuing mystery, romantic complications, and a heroine whose past is revealed in pieces. The books work best in order, since the relationships and the larger threat develop across the series rather than ending neatly after the first case.

Start with Demons and Deception to meet Hailey before the magical world demands more from her than she planned to give.
