Orphaned at birth, Eliza Sommers is raised in the British colony of Valparaíso, Chile, by the well-intentioned Victorian spinster Miss Rose and her more rigid brother Jeremy. Just as she meets and falls in love with the wildly inappropriate Joaquín Andieta, a lowly clerk who works for Jeremy, gold is discovered in the hills of northern California. By 1849, Chileans of every stripe have fallen prey to feverish dreams of wealth. Joaquín takes off for San Francisco to seek his fortune, and Eliza, pregnant with his child, decides to follow him.
