The Third Wheel by Kristin Lance

Mira is my ride or die, my soulmate, my partner in crime. We’re like two peas in a pod, and even our faults complement each other. Together, we run a quaint little bookstore in Hazy Cove, our own little paradise in the Pacific Northwest. And I’m madly in love with her.
The only thing marring perfection? Her annoying, alpha-hole of a husband, Gunnar.
Yeah, I’m the ultimate third wheel.
To make matters worse, Mira wants Gunnar and I to be friends and is always trying to set up our bromance.
Let’s be real, two men couldn’t be any different: Gunnar owns a motorcycle shop, I own a bookstore. Gunnar has tattoos, I… well, okay I also have tattoos, but mine are intellectual. And we can’t agree on anything.
But as much as I want to hate him, Mira adores him and can’t seem to see past his overbearing ways. So when she begs me to come along on their next adventure, a camping trip in the wilderness, how can I say no? I know things will be awkward, but I can never deny her anything.
But on our camping trip, Gunnar’s tough guy facade finally cracks, revealing that he’s different than I ever expected. He’s oddly sweet, bisexual, and definitely into sharing his wife with me.
Suddenly, I’m in way too deep. Of course, I’m even more in love with her, but that’s not all — he’s on his knees, asking for something I never expected to give. And I might want both of them.

But that’s not a thing… is it?
