Rule Breaker by Haven Rose

As a veteran cop, Keller Charles is not only rough around the edges, but also jaded. He’s seen the bad in people, including his own father, and it taught him valuable lessons. In his opinion, work is synonymous with breathing, and his tactics don’t always translate well, nor do his morals. Which is why he’s training rookies, punishment for his reluctance to be a team player.
Emerson Malone has a mind of her own and isn’t afraid to speak it…now. She refuses to be a trophy wife as her parents expect, preferring to forge her own path despite the repercussions. But she never counted on the obstacle that is Keller standing between her and a badge.
The attraction is immediate, not to mention forbidden. She’s the untouchable princess, yet his caresses seem welcome, and he’s the grouch that won’t admit what she does to him.
Together, they’ll break all the rules.
