The star garden / Nancy E. Turner.

Enhanced descriptions from Syndetics:

From the bestselling author of These Is My Words comes this exhilarating follow-up to the beloved Sarah's Quilt . In the latest diary entries of pioneer woman Sarah Agnes Prine, Nancy E. Turner continues Sarah's extraordinary story as she struggles to make a home in the Arizona Territory.
It is winter 1906, and nearing bankruptcy after surviving drought, storms, and the rustling of her cattle, Sarah remains a stalwart pillar to her extended family. Then a stagecoach accident puts in her path three strangers who will change her life.
In sickness and in health, neighbor Udell Hanna remains a trusted friend, pressing for Sarah to marry. When he reveals a plan to grant Sarah her dearest wish, she is overwhelmed with passion and excitement. She soon discovers, however, that there is more to a formal education than she bargained for.
Behind the scenes, Sarah's old friend Maldonado has struck a deal with the very men who will become linchpins of the Mexican Revolution. Maldonado plots to coerce Sarah into partnership, but when she refuses, he devises a murderous plan to gain her land for building a railroad straight to Mexico. When Sarah's son Charlie unexpectedly returns from town with a new bride, the plot turns into an all-out range war between the two families.
Finally putting an end to Udell's constant kindnesses, Sarah describes herself as "an iron-boned woman." She wants more than to be merely a comfortable fill-in for his dead wife. It is only through a chance encounter that she discovers his true feelings, and only then can she believe that a selfless love has at last reached out to her. . . .
