Sexy Dirty Cowboy by Elle Thorpe

Rem ‘Viper’ James knew his secrets wouldn’t stay buried forever. He just never expected to be arrested in front of 20,000 screaming rodeo fans. Dragged into an interrogation room, Rem is given an ultimatum: testify against his old motorcycle club or face another stint in a cell.
There’s only one answer when going back inside means leaving in a body bag.
Whitney Nicholson was left humiliated after her boyfriend’s secret life was exposed. After all, as a police detective, she should have seen it coming. So it’s salt in the wound when Whitney’s boss sends her to babysit an ex-MC member, who’s been masquerading as a cowboy on the rodeo circuit.
To add insult to injury, they’re going into hiding in a tiny country town. As a married couple.
Whitney has no interest in a relationship: pretend or otherwise. But as small-town life begins to grow on her, so does Rem. There’s something sexy, dirty, and oh so hot about the man whose life she’s supposed to protect.
However, when mysterious and disturbing crimes begin occurring around them, Whitney will need to decide if her cowboy is worth risking not only her heart, but also her life.
