Homecoming — Rick R. Reed

After losing his partner Toby, Chase faces a long, painful road back to life and love. At first, he doesn't see how he can go on, but then Chase and Toby's old friend Mike cajoles him into returning to Chicago for the annual International Mr. Leather Competition. There Chase revisits a world of hot, casual sex that he had forgotten existed, meets a friend who cares more for him than he ever realized, and discovers the possibility that he might yet find his way home.
