He's my best friend's older brother. My boss. And now my new roommate... In the hospital, death always comes in threes. Apparently, so do mistakes. Mistake number one? My fiancé, who I just learned is cheating on me. So much for being the strong, in control doctor who's always on top of her game... Mistake number two? Knocking on the wrong door. The door I thought still belonged to my best friend now belongs to his older brother, my obnoxious, overly cocky, gorgeous-as-sin attending physician, Carter Fritz. The billionaire playboy gives me a place to stay, and a shoulder to cry on. But when he makes me feel seen for the first time in I don't even know how long, I tell myself I don't regret what was easily the hottest, most earth-shattering night of my life. That is until mistake number three comes along... and I'm staring down at a stick with two pink lines. Having a baby at this stage of my residency could cost me everything I've worked so hard to build. But Carter? He's undeterred. He doesn't just want more; he wants it ALL. Including me. But what happens if following my heart turns out to be my biggest mistake of all?
