Sun is ready to leave his village in China for America, the place known as Gum Saan, Gold Mountain. His father warns him, though, that passage will not be easy. Because of the 1882 Chinese Exclusion Act, new immigrants like Sun are detained at Angel Island until they are called to take a difficult oral exam before they can "land" - leave Angel Island and go ashore. On the boat, Sun had studied maps of his village and memorized facts about his ancestors. But as the weeks pass in detainment, the map's compass points swirl in his memory, and Sun worries that he will lose his direction and be turned away. The oil paintings are rich with historical details in this vivid recounting, based on the author's father-in-law's experiences, of a disturbing chapter in Chinese American history.
