Secret Enemy by Katie Reus

He thinks she’s out of his league.

Lyosha Vasiliev met Mila by chance, and now she’s all he thinks about. But the two couldn’t be more different, so Lyosha won’t go there. As a security expert, he skirts the law on the regular. Unlike Mila, the newest employee at Red Stone Security, who spends her free time volunteering at an animal shelter. Despite his determination to stay away from her, when it becomes clear his past has come back to haunt him—and poses a threat to her—Lyosha immediately steps in. And he’ll cross any line to keep her safe.

But he can’t seem to walk away.

Mila met Lyosha when he brought in a half-starved stray cat to the shelter she volunteers at. He tries to act tough—and okay, he is. He should be the last man she wants, but she loves his sexy tattoos, gruff demeanor, and that he has a marshmallow inside that only she gets to see. When someone threatens her, he’s convinced it’s linked to his past. He’s made it clear that he’ll protect her with his life—but he won’t give her his heart. Not when he blames himself for bringing danger to her doorstep. Except Mila isn’t the kind of woman who walks away from what she wants. And Lyosha finds himself unwilling to let her go without a fight.
