Disaster strikes DEA Agent Holt Donovan twice, when a gunfight ruins his mission and a car crash kills his brother and sister-in-law. Home on the Colorado ranch to raise his infant nephew, Holt enlists a nanny-Maddy McCoy, the woman who once jilted his brother. The world-traveling photographer never expected to return to Colorado, the only real home she ever had, and to the man she never forgot. Burned out from covering too many starving children and refugees and short on funds, Maddy agrees, vowing to keep her heart safe. What neither of them knows is that by bringing her into his home, Holt has placed her in the crosshairs of a killer. As Holt and Maddy cope with their desire for each other and the resentments of the past, their investigation into the brother's death leads them into escalating danger and a shocking discovery.
