Grey's Hidden Fire (Firehouse Six #1)
Draven St. James

Mica has one rule…keep his work life and his personal life separate. It was easy enough to follow until he meets Grey and finds that his rule can’t stand up to the fire that Grey ignites. There’s one big thing standing in the way of all of his lust filled musings. Grey is straight.
In a profession where being gay is often kept quiet Grey must come to terms with his growing attraction to Mica. How much is he willing to sacrifice? Can they come together before someone’s hatred threatens to destroy them both?
