From the 1850s, as the United States pushed west, Chinese migrants met ordinary Americans for the first time. Alienation and xenophobia lost the US this chance for cultural and economic enrichment-but America gave the Chinese new perspectives and connections. They developed a dream of their own.

As teenagers, Hugo Wong's great-grandfathers fled poverty in China for California. A decade later, they were excluded from the States. They helped establish a Chinese settlement across the border in Mexico, led by a world-famous dissident-in-exile with visions of a New China overseas. They would be among the Americas' first Chinese magnates, meeting with presidents, generals and missionaries, living through astonishing victories and humiliating defeats. The bitterest of all would be the colony's tragic demise amid a violent Mexican revolution, leading to the largest massacre and deportation of Chinese in American history.

This epic 100-year drama follows the lives of the author's ancestors, via untouched personal papers. Though no Chinese group had ever gained such influence over a Western population and territory, their home in Mexico would long be forgotten. Today, this family story is reborn: one of nationhood, state racism and a turbulent century; of exile, grit and new ways of belonging.
