My 10 year old son, and I listened to "Hatchet" on Audio CD format, while driving from WA State to eastern B.C., Canada. Read splendidly by Peter Coyote, it is a captivating story of a boy's survival in the northern Canadian woods. My son was mesmerized. He and I thoroughly enjoyed the story, and it helped time pass quickly on our long drive north. I think the entire audio version is just over 3 hours, with 3 CD's. I highly recommend this book for any youngster who's curious about learning survival skills, and imagines what it would be like to have to survive on their own.
