Demon Fire. Evergreen Witches, #3

Juniper Evergreen has spent her life struggling to control a power she never asked for. Ethan Warwyck is a half-demon veteran who turned battlefield instincts into a deadly talent for hacking the city's supernatural underworld. When their worlds collide, the chemistry is instant. Pulled into a dangerous romance that neither community will accept, Juniper and Ethan must navigate treacherous secrets that could expose the entire hidden city.
As a shadowy force closes in, alliances fracture and loyalties are tested. To save the people they love, they'll risk everything-reputation, freedom, even their lives. A pulse-pounding urban fantasy of magic, menace, and a love that refuses to be extinguished. In Lexington's darkest hour, only one thing can stop the city from burning: them.
