Set in the Wild West during frontier times, Yipee's Gold Mountain is told by Yip Yee, an orphaned Chinese ex-railway laborer who hopes to be a cowboy, and Na-tio, an Apache warrior-apprentice who is recovering from his first botched raid. Through alternating chapters both characters reveal different sides of the story, as their mutual suspicion turns to friendship. Together, Na-tio and the tiny, determined Yip Yee face down a wolf attack, a sinister bounty hunter and greater challenges still, in this hard scrabble world of fortune-seekers, soldiers and warriors. Through all this, Na-tio must cope with a terrible crisis for his people, and Yip Yee is guarding a big secret.
