Thanks must go to Darren for spotting this.
Mark the mountain guide is written by Mark Seaton a qualified mountain guide, and is an adventure story for kids. Beautifully illustrated throughout the story tells of how Mark and the gang are cut off by an avalanche and how they make their return home from the alpine hut they were staying in.
It's more than a story though. Told in a rather matter of fact way, the book describes the danger but also the precautions and procedures used to negotiate safely in this type of environment. Accompanying the book is a toy karabiner and piece of rope for your audience to practice tying clove hitches and figures of eights. There's an appendix on knot tying, and another on how avalanches are caused and happen.
With the subject matter and technical content in mind, I think that this book would appeal to children in the five to eight year old age range. That's not to state that younger one's won't find the story in itself entertaining.
The acid test of course comes when I read the book to my son once he's opened it for Xmas.
