Sarah Mims stood alongside her husband and fellow Texans for the entirety of the thirteen grueling days of battle at the Alamo. Upon capture in the aftermath, she and the other women are swept up in Mexican wagons bound for an unknown future. Intercepted by a group of Texan scouts, the women are rescued and taken to General Sam Houston. It is there at camp that Sarah decides her journey in Texas is not yet over. Saddling up with a group of Rangers, she becomes their appointed nurse. Learning to live on the prairie and overcoming her grief, she becomes close with kin-spirit Lee Anderson, a Ranger with a story similar to her own. As the war rages on, Sarah questions her placement amongst the men and learns that there are many more threats at play than Santa Anna and his army; some are even sleeping in the same circle.
