Loyalty Under Fire by Trish McCallan

Rio: He betrayed her once.
Listened to the wrong damn people and walked away when she needed him most. That was on him. He’d live with that mistake for the rest of his life.
But she was back again with a killer on her heels, and he’d break anyone who tried to hurt her. He’d make them bleed. He’d make them disappear if he had to.
And when it was over, he wasn’t letting her go.

Becca: He came close to breaking her with his desertion. But in the end his defection made her stronger. It taught her she could survive anything. She could survive without him.
Now she’s back, ready to serve justice for a decades-old murder.
And he wasn’t getting in her way…no matter how much she craved his mouth on hers…his body pressed against hers…
He burned her once—she wasn’t giving him another chance.
