Let it Rain Coffee by Angie Cruz

Angie Cruz has established herself as a dazzling new voice in Latin American fiction, her writing compared to Gabriel García Márquez's by The Boston Globe. Now, with humor, passion, and intensity, she reveals the proud members of the Colón family and the dreams, love, and heartbreak that bind them to their past and the future. 
Esperanza risked her life fleeing the Dominican Republic for the glittering dream she saw on television, but years later she is still stuck in a cramped tenement with her husband, Santo, and their two children, Bobby and Dallas. She works as a home aide and, at night, hides unopened bills from the credit card company where Santo won't find them when he returns from driving his livery cab. 
When Santo's mother dies and his father, Don Chan, comes to Nueva York to live out his twilight years with the Colóns, nothing will ever be the same. Don Chan remembers fighting together with Santo in the revolution against Trujillo's cruel regime, the promise of who his son might have been, had he not fallen under Esperanza's spell.
