Moving to America turns H&à's life inside out. For all the 10 years of her life, H&à has only known Saigon: the thrills of its markets, the joy of its traditions, the warmth of her friends close by, and the beauty of her very own papaya tree. But now the Vietnam War has reached her home. H&à and her family are forced to flee as Saigon falls, and they board a ship headed toward hope. In America, H&à discovers the foreign world of Alabama: the coldness of its strangers, the dullness of its food, the strange shape of its landscape, and the strength of her very own family. This is the moving story of one girl's year of change, dreams, grief, and healing as she journeys from one country to another, one life to the next.
