Mariposa by Lexie Axelson

I made it into the special forces course, but there are three problems.
Problem number one? One of my instructors is the infamous Special Operator Beast—a man everyone fears due to his cold heart and polished career. He loathes being away from his team, which makes graduating nearly impossible for all of us, mainly his least favorite student, me.

Problem number two? My heart skips a beat whenever I look into his cruel eyes, and my blood heats whenever he’s near me. He’s tall, scarred, and a devastatingly irresistible man who never smiles.

Oh, and problem number three? He’s my ex-boyfriend’s dad.

We try to stay out of each other’s way to make our reckless attraction fade, but fate keeps bringing us together. The military calls me The Unbreakable Soldier, but falling for Kade O’Connell might be my undoing.
