I read "How to Talk . . ." by the same authors and was blown away by how powerful it's implementation was in my family. I wondered, should I bother reading the first book that inspired it? I'm so glad I did.
This book explains how the authors worked through their family issues with the help of Haim Ginott. It humbly shows how two moms dealt with their anger and learned how to be truly constructive.
Read this book--you will not be sorry!
