in las uvas can you explain me more about the vineyard

Esperanza recounts the past year of her life, marking time by growing seasons rather than months.The novel is cyclical, just like the growing seasons, and the end is similar to the beginning. Both the first and last chapters take place during the grape season, showing that within one year, Esperanza’s life has come full circle. Mama recovers and Abuelita finally escapes from Mexico, meaning that the Ortega family has completed the transition to their new life in the United States.
