Twice a Target — Susan Vaughan

NEW COVER!
Part of a series, but a stand-alone novel with its own conclusion. No cliff-hangers.

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 a Mexican cartel kingpin ends in a disastrous gunfight. Before the task force can regroup, the deaths of Holt's younger brother and sister-in-law send him home to run the 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-fiancée. She arrives to offer condolences. The world-traveling photographer never expected to return to Colorado but couldn't resist returning to the Rockies and to the man she never forgot. Holt taunts her about her past defection and her jet-set ways until her grief 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, 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 killer. As Holt and Maddy cope with their desire for each other and the resentments of the past, their investigation leads them into escalating danger and a shocking discovery.
