Jade Moon is a Fire Horse -- the worst sign in the Chinese zodiac for girls, said to make them stubborn, willful, and far too imaginative. But while her family despairs of marrying her off, she has a passionate heart and powerful dreams, and wants only to find a way to make them come true.

Then a young man named Sterling Promise offers Jade Moon and her father a chance to go to America. While Sterling Promise's smooth manners couldn't be more different from her impulsive nature, Jade Moon falls in love with him on the long voyage. But America in 1923 doesn't want many Chinese immigrants, and when they are detained at Angel Island, the "Ellis Island of the West," she discovers a betrayal that destroys all her dreams. To get into America, much less survive there, Jade Moon will have to use all her stubbornness and will to break a new path... one so brave and dangerous, only a Fire Horse girl could imagine it.
