When a ghost from my past walks back into my life, I jump at the chance to reconnect. My husband, Clark, and I are polyamorous, but for us that has never meant finding a third to join our happily ever after. We weren't looking for a triad. It wasn't what either of us wanted. Until Ethan. My estranged childhood best friend walked out of my life a decade ago when his family rejected him for being trans. With him back, it feels like he never left. Now, I want everything with the man I promised forever and the first boy I ever loved. Too bad the timing isn't ideal. Clark and I are both struggling with work stress and it's taking a toll on my mental health. Ethan might be everything neither of us knew we were looking for, but how can I convince Clark of that when I'm spiraling and all he sees is how losing Ethan the first time destroyed my trust?
