Charles is only supposed to guard Maude and her sisters to their destination. He should have guarded his heart.
Still raw with grief after their father's funeral, Maude Lancaster and her two younger sisters refuse an ultimatum from their ill-intentioned uncle. Since it’s a new century and women can travel unchaperoned, they decide to flee out west to live with their older brother. Their aunt hires Charles for protection, but Maude soon finds that her greatest danger is in losing her heart to a man she may never see again.
Former Pinkerton agent Charles Merrick has an opportunity for a new job in San Francisco. When his mother’s friend asks to hire him to escort her three nieces across the country, he agrees. Their destination is only a little out of his way. But Charles faces a stumbling block in his attraction to Maude. He's never felt such a connection with a woman before, but they’ve only known each other a few days. It’s too soon for there to be anything real between them. He can continue on to his dream job, or he can stay to see if Maude is the one. He can’t do both.
