From the back cover:
"Young Naomi leaves the Far East to search the New World for the family she's never known. Her search takes her deep into the West—which is a good thing, because the agitated horse that comes into her possession will only run in that direction!
Things get more twisted when Naomi interrupts a duel between an outlaw and a bounty hunter—and each of them suddenly believes he is related to her. The outlaw thinks Naomi's his sister and the bounty hunter is convinced he's her dad!"

Naomi, a young Japanese woman, arrives in the Wild West in search of her parents. She doesn't know the customs of cowboys, but is not discouraged. Can a little Japanese girl survive the savage West?
