Firestorm (Fighting Fire #1)
Laura Harner

Leaving San Francisco to take a part-time position as a law enforcement ranger makes no sense at this stage of his life, but after Scott’s critical burns, Robby moves to Flagstaff anyway—to take up residence at Mountain Shadows—which has nothing to do with his long-buried feelings for his ex. Despite the white-hot attraction that still burns between them, too much is at stake for Robby to take that chance. Again.
Torn apart a dozen years ago by an unlimited ability to cause each other pain, each man believes the relationship door is firmly closed, but when life brings them back together, Scott is still the irresistible force to Robby’s immovable object, and where there’s smoke…there’s fire.
