Mariposa

A woman has won a place on a special forces course, and three complications come with it. The first is an instructor known as the Special Operator Beast, a man his colleagues fear for his cold manner and polished career. He hates being away from his team, and that resentment makes graduation close to impossible for every trainee.

She is his least favorite student. The military calls her The Unbreakable Soldier, a reputation that is about to be tested.

The instructor is Kade O'Connell. He is tall, scarred and never smiles, and she feels her pulse jump whenever she meets his hard stare. Her body responds to him whenever he is close, and the second complication is that she cannot stop it.

The third is that Kade is her ex-boyfriend's father. Both of them try to keep their distance so the attraction will fade, but circumstances keep putting them in the same place.

This is the first book in the Queens Command Series, set in the Scarred Executioners universe. It is a military romance with a forbidden, slow-burning pull between a recruit and the instructor who can end her career.
