Hurt Me Not by Davidson King

As a lieutenant at the Fool’s Pass Fire Department and a single father, Easton Kooper’s life revolves around his children. When he receives an urgent call from his son’s doctor, it upends Easton’s world. Suddenly, barreling into a burning building sounds like a piece of cake. With no idea of what to do or where to turn, he’s never felt more lost. And then in walks the answer he didn’t know he needed: a gorgeous fae with an angelic smile, bearing grand promises to turn the Kooper family’s life right side up again.
Finch knows the rules: don’t fall in love with a human. That’s always been simple enough to follow—at least until the Kooper family. Despite his best efforts, Finch grows attached to Easton and his children…attached enough that he’s tempted to turn his back on the fae and their laws completely.
Before long, the pair must brace themselves as both their worlds seek to destroy them. When the darkness crashes down, it’ll take every ounce of defiance and magic Finch has to keep the Koopers safe. Faced with immovable magic and unspeakable danger, is there really any way Finch and Easton’s love can prevail?
Fighting it is hopeless, but embracing it could mean ruin for them all.
