The Dutch House by Ann Patchett

At the end of the Second World War, Cyril Conroy combines luck and a single canny investment to begin an enormous real estate empire, propelling his family from poverty to enormous wealth. His first order of business is to buy the Dutch House, a lavish estate in the suburbs outside of Philadelphia. Meant as a surprise for his wife, the house sets in motion the undoing of everyone he loves. Cyril's son Danny and his older sister Maeve are exiled from the house where they grew up by their stepmother. The two wealthy siblings are thrown back into the poverty their parents had escaped from and find that all they have to count on is one another.

Esperanza rising by Pam Muñoz Ryan

Esperanza thought she'd always live a privileged life on her family's ranch in Mexico. She'd always have fancy dresses, a beautiful home filled with servants, and Mama, Papa, and Abuelita to care for her. But a sudden tragedy forces Esperanza and Mama to flee to California and settle in a Mexican farm labor camp. Esperanza isn't ready for the hard work, financial struggles brought on by the Great Depression, or lack of acceptance she now faces. When Mama gets sick and a strike for better working conditions threatens to uproot their new life, Esperanza must find a way to rise above her difficult circumstances-because Mama's life, and her own, depend on it.
