In Along the Rio Grande: Love On The Santa Fe a recently widowed Susanna Jenkins has decided to follow her family to the booming town of San Marcial, New Mexico, for a fresh start and to aid in her family's sudden change in fortune. They are tasked with managing her uncle's new Grand Hotel, and it takes all her patience to try to help her parents see the good of their circumstances and relinquish their sense of entitlement.
She's hopeful when her brother becomes determined to get a job and make his own way, and she feels drawn to his kind boss, Owen Turner, who works as a boilermaker for the Santa Fe's train shops in town. But the hard work only seems to fuel her brother's anger, and his rough new friends give her pause.
When misguided choices put Susanna's family in an even more precarious situation, she worries her help has only made things worse. Leaving her family to fend for themselves seems like the best option, but how can she walk away from the true friendships - and love - that she's found?
