The Compatibility Matrix by Ms. Heather Collins Grattan

I gracefully got a comment and an email from the author (Type B woman).

The Compatibility Matrix: The Qualities of YOUR Ideal Mate
by Heather Collins Grattan (Author), Joseph Christiano (Foreword)

This book is a romantic book of seeking the ideal partner, that devotes whole chapter 8 to the blood type. What is different from Japan is that there are religion and politics in the elements of compatibility (Compatibility Matrix).

She adopts a method of summing up the scores of each element and judging compatibility. Whether it is American style or Type B style, I wonder. By the way, its blood-type compatibility closely matches Mr. Nomi's "lead = care relationship".

Perhaps this book may be sold if well translated into Japanese.
