Although this book was easy to read, I found it a bit too general and woolly. It is easy to see yourself in all four categories and it is difficult to put yourself in one. Sometimes when methods are generalised too much for ease of use they lose their effectiveness. It is quite difficult to accept that 25% of the population all love in the same way and can be given the same solutions. I was a little bit disappointed not to find anything really useful, but other people might be able to relate to the letters more easily. Any book that sets out to help people improve their relationships is extremely welcome, and while this book might not be for me, it might be just the thing for many others. Good luck and thank you
