Hi Moonsong: I think you will enjoy that book. It is really user friendly as well, which is always a plus in my life.... Several of the people on my group bought it too and they love discovering what it is that makes the relationship tick, or not tick... I also am a fan of Celeste Teal's books because she has done quite a bit of work with the Vertex and the Nodes in comparison charts... She loves to research..
Her book: Cheers, Kiwi
