It's 1926, and the one thing eleven-year-old Lexie Lewis wants more than anything is to leave Portland, where she is living with her strict grandparents, and rejoin her mother, a carefree singer in San Francisco. But Mama's new husband doesn't think a little girl should live with parents who work all night and sleep all day. Lexie's class has been raising money to ship a doll to the children of Japan in a friendship exchange, and when Lexie learns that the girl who writes the best letter to accompany the doll will be sent to the farewell ceremony in San Francisco, she knows she just has to be the winner.
