The Gay Best Friend by DiDomizio

Bridesmaids meets The Guncle in this clever LGBTQIA+ romantic story by the author Steven Rowley calls "unforgettable" 

As a people-pleasing gay man, thirty-year-old music lawyer Domenic Marino is an expert at code-switching between the hypermasculine and ultrafeminine worlds of his two soon-to-be-wed best friends: handsome sports attorney Patrick Cooper and glamorous beauty editor Kate Wallace. But this summer—reeling from his own failed engagement and tasked with attending both their bachelor and bachelorette parties at the Cooper family’s idyllic shoreline estate in Mystic, Connecticut—Dom is anxious about having to play both sides. 

Kate has been pressuring him to keep the bachelor party clean and report back to her when it’s over, so Best Man Dom accordingly develops a G-rated itinerary. But once Patrick’s rowdy groomsmen show up—including a surprise visit from Patrick’s old frat brother, handsome and definitely-not-out PGA star Bucky Graham—chaos quickly ensues. By the time Dom returns to the Mystic house for the bachelorette party, he has accumulated a laundry list of secrets that threaten to destroy everything—from the Cooper-Wallace wedding to Bucky’s golf career to the one thing he hasn’t been paying nearly enough attention to lately: his own life.
