John is scared. His mom married the man from Minnesota, and now he has to leave the Navajo Reservation. John has never lived off the Reservation. What will it be like? How will he measure up to the people who live outside of the Four Sacred Mountains?
But John's grandfather tells him he will be all right, for he has something very special to take with him; he has the unbreakable code—the code that saved thousands of American lives in the Pacific during World War II, invented using the then unwritten Navajo language.
The Unbreakable Code has sold over 150,000 copies and has won several national awards.
Order The Unbreakable Code from Amazon.com or from your favorite local bookstore.
