Blake

I don’t do relationships, but I’m excellent at casual hookups. That’s not to say I’m a jerk. Not at all. I respect women—all women—and I know the value of love. But I’m married to my job as a physician. In fact, I’m married to the hospital, having a full-time affair with the clinic, and my family is my side piece. I don’t have time for a relationship with a woman.

But then the most beautiful human I’ve ever laid eyes on walks onto my plane, and my world tilts. Thanks to a Montana snowstorm, I spend one incredible night with Harper but wake up alone. She never told me her last name. She’s just … gone. It would figure that the one woman I could see myself breaking my own rules for is the one I can’t have.

Harper

It’s time for me to come home to Montana to help take care of my dad and pick up the slack for my siblings. I’ve been gone for a long time, but this beautiful corner of the world is my home. I’m excited to start my job as a NICU nurse at Bitterroot Valley General and begin a new chapter in my life. A fresh start. A clean slate.

Then he walks into the room, and it’s suddenly hard to breathe. Blake was the one-night stand who still haunts my dreams. The man can do things. Amazing things. But I never thought I’d see him again. Okay, that’s a lie. I knew he worked at this hospital, but he’s an ER doctor. I’m in a different department, so I planned to avoid him. Yet that didn’t last more than the first hour of my first shift.

Now, he’s pursuing me and saying things like forever. But with a past like mine, can I trust that he won’t tire of me and leave? Or is this finally my happily ever after?
