The Guardian's Mission

Danger draws one woman into an undercover agent's arms in the first Sinclair Brothers romance thriller from the New York Times–bestselling author.

"Ma'am, I'm not one of the bad guys."


So says the handsome man Martha Gabler encounters near her isolated mountain cabin. Tristan Sinclair claims he's an ATF agent working undercover. And that if she doesn't play along as his unexpected girlfriend, they'll both end up dead. Nursing a broken heart, Martha knows a thing or two about love that isn't real. Still, she calls up all her faith and turns her shaky trust over to Tristan. Soon she's hoping he'll take on a new mission: guarding her for the rest of her life.
