Some days, ten-year-old Margaríta Sandoval feels as if the wind might blow her away. The country has been gripped by the Great Depression, so times are hard everywhere. Then she has to leave her família in New Mexico—especially her beloved Abuelita—to move to Fort Steele, Wyoming, where her father has taken a job on the railroad.

When Margaríta meets Caroline, she's excited to have a friend her own age in Wyoming. But it often seems like Caroline, like many other people in town, doesn't understand or appreciate the Sandovals' Hispanic heritage. At the same time, the Sandovals discover that Abuelita might lose her home unless they can pay off her tax bill. Can Margaríta keep her friend, help her family in New Mexico, and find a place in Fort Steele for good?
