A great adventure tale.  Nelson alternates between the stories of 2 boys.  Tirio was born in the Amazon jungle, but raised in the United States.  As he approaches his 13th birthday, he feels the strong call to return home.  Luka was also born in the Amazon.  His approaching 13th birthday brings a test that will determine his and his family’s place in the tribe.  Both boys must face challenges beyond their imagination.

This would be an excellent book for late elementary/early middle school readers.  The unique culture and setting are refreshing, and the boys’ hard work, sacrifice, determination and love of family are to be admired.
