Oath of Valor by Brittany Cournoyer

If asked, Larry Armstrong would say that failure isn’t in his DNA, but you only have to look at his relationship with his son to know it’s a lie. Going undercover to catch the country’s worst criminals is far easier than fixing the mistakes he’s made with Brice. It didn’t help his situation any when he unknowingly sleeps with his son’s best friend.

If asked, Elliot Pritchard would say that he has a type, and its name is Trouble. From hookups gone wrong to being in the wrong place at the wrong time, Elliot can’t catch a break. After a brutal attack nearly kills him, he finds himself staying with the last person he ever expected to—Larry.

Complicated doesn’t begin to describe the situation the two men find themselves in, and things only get harder when Elliot witnesses a violent crime and needs Larry’s expertise to keep him alive. Tempers and tension build as Larry and Elliot try to ignore the chemistry burning between them, but they’d have a better chance of finding a snowball in hell. The two men realize they could have something special if not for two important things: Brice’s feelings and a madman with Elliot in his sights.
