He doesn't want a woman he can't trust, and she doesn't want a man who won't let himself trust her. DEA Agent Holt Donovan's mission to trap Mexican cartel kingpin El Aguila ends in a disastrous gunfight. Before the task force can regroup, the death of Holt's younger brother and sister-in-law in a car crash sends him home to run the family's debt-burdened Colorado ranch and raise his infant nephew. Grief-stricken and suspicious, he sets out to prove the crash was no accident but murder. He has to fend off a custody suit by the baby's grandparents and needs child-care help in a big way, but not from the pampered female who jilted his brother eight years ago. Enter Maddy McCoy, Holt's first love and his brother's ex-fiancee. Emailed by a friend about the deaths, she arrives to offer condolences. The world-traveling photographer never expected to return to Colorado but couldn't resist returning to the Rockies, the only real home she ever had and to the man she never forgot. Holt taunts her about her past defection and her jet-set ways until her grief over his brother's death makes him back off. Looking to Maddy for help is Holt's last resort and he expects her to bolt at any time, but he asks her to stay on as nanny. Burned out from covering too many starving children and refugees, short on funds, and stranded, Maddy agrees, but she'll remain only as long as she can keep her heart safe. What neither of them knows is that by bringing Maddy into his home, Holt has placed her in the cross-hairs of a vengeful 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."
