I really enjoyed this even though I have never been to an Aikido class. Written as a novel, this is entertaining in its own right but the Aikido techniques and theory are so well-described that any martial artist will learn something useful here, and this must be an absolute treasure for the Aikido practitioner. The author's own skill shows through in his ability to bring the techniques and principles to life in a simple and interesting way. If I knew how to operate my Kindle I could have probably zipped back and forwards to the comprehensive glossary whenever the Japanese terms were used, but I guess the terms will be familiar enough to Aikido students. Highly recommended.
