Query: A great book!

I thoroughly enjoyed this book! I felt like I was on the mountain with Bear Grylls. I liked how he described life at Base Camp and the pure boredom and anticipation he felt waiting for his body to acclimate. He allows the reader to see his fears, insecurities, hopes and dreams. He shows you that he is a real person climbing this awesome mountain. A non-climber can follow the technical aspects of the book very easily.
