Hardest (Hard Series #5)
Jamieson Wolf

Years ago, Owen and Daniel parted. Best friends for years, they each gave into their attraction one summer to find love, only to lose it when the summer ended. Yearning to fill the void he feels in himself, Owen has tried anonymous sex, quick flings and dating to get his mind off his first love. But all to no avail.
Even all these years later, even after all the hurt, Owen still carries a torch for Daniel. The only problem is, Owen can't find him. So when Daniel tracks Owen down and finds him in a bathhouse, everything Owen thought he knew is about to change forever.
