San Francisco, 1906. In a city bustling with newly minted millionaires and scheming upstarts, two very different women hope to change their fortunes: Gemma, a golden-haired, silver-voiced soprano whose career desperately needs rekindling, and Suling, a petite and resolute Chinatown embroideress who is determined to escape an arranged marriage. Their paths cross when they are drawn into the orbit of Henry Thornton, a charming railroad magnate whose extraordinary collection of Chinese antiques includes the fabled Phoenix Crown, a legendary relic of Beijing's fallen Summer Palace. His patronage offers Gemma and Suling the chance of a lifetime, but their lives are thrown into turmoil when a devastating earthquake rips San Francisco apart and Thornton disappears, leaving behind a mystery reaching further than anyone could have imagined . . . until the Phoenix Crown reappears five years later at a sumptuous Paris costume ball, drawing Gemma and Suling together in one last desperate quest for justice.
