Nugget Cullen is the beautiful and headstrong daughter of a gringo rancher in post-Civil War California. Nugget is in love with the handsome young caballero Hipolito Mendoza, heir to one of the great land-owning California families, and he loves her—but how can a Mendoza marry a gringa and a heretic? Fields of Amaranth is set during a time of social and economic turmoil. The gringo culture is on the rise, and the old native Californians are being pushed out. Shaken by natural disasters and racial tensions, the young city of Los Angeles is trying to find its identity, tame the cycle of flood and drought, and attract the railroad that will finally put it on the map. Nugget is determined to have the man she loves, but the odds—and her own impulsive nature—are stacked against her. Her passionate actions, played out against a backdrop of violent change, will shape the woman she is to become.
