Josefina is delighted when Tía Dolores returns to the Montoyas rancho. But soon after she arrives, a flash flood kills hundreds of the family's sheep. Tía Dolores suggests that the Montoyas could recover from this terrible loss by starting a weaving business - something Mamá never would have done. But Papá likes the idea. Then Tía Dolores decides to teach the girls how to read. Mamá didn't read, but Josefina is excited to learn. Then she begins to worry. Will all these changes make the girls forget Mamá?
