I highly recommend the audio for this book because of the Navajo songs and passages of the text. It was really wonderful to actually hear the language that's at the heart of this story. It's also a great choice for anyone who's interested in combat stories, since much of the book takes place during battles in the Pacific theater of WWII. 

I found the whole book fascinating, and while it's a fictional account, the author's afterward points out that all the people aside from the main character are real soldiers. I'm definitely going to look for some non-fiction on the code talkers next.
