Re: i need help finding a book
Three books that deal with relationships and Aikido don't seem to fit your physical description. The first is Aikido in Everyday Life: Giving in to Get Your Way Terry Dobson, Victor Miller, ~ North Atlantic Books 01 January, 1993 ~ ISBN: 155643151. The second is The Way of Aikido: Life Lessons from an American Sensei George Leonard, ~ Dutton Books 01 May, 1999 ~ ISBN: 0525944133. The third is Magic of Conflict Thomas Crum, ~ Touchstone 01 January, 1988 ~ ISBN: 0671668366.
A book that seems close to your physical description of the sumi circle cover is Aikido and the Harmony of Nature Mitsugi Saotome, ~ Shambhala 1993 ~ ISBN 0-87773-855-6. But that book has a cream color cover and deals more with the nature of Aikido.
Perhaps if you could give a closer description. Was it paperback or hardback. Was the author American or Japanese? Besides relationships, what specifically did the chapters cover? Do you know when it might have been published? Do you know someone who might have seen you with the book and could tell you the title?
Good luck with your hunt.
