A powerful approach to childrearing relationships based on the Imago theory developed by the authors. I think the content is great, but reading it is a bit like slowly choking down a heavy, weird-tasting health food bar because you know it's good for you. I read an older edition, so I don't know if anything's changed, but I agree with the criticisms that it is narrowly focused at "traditional" married two-parent heterosexual couples as parents. The religious overtones can also be off-putting.
That said, the processes for enhancing our understanding of ourselves and our compassion for our children presented in the book are so valuable that it's easy to forgive the dense writing and hints of evangelism. I'd recommend this book to anyone seeking an opportunity for real self-revelation; intentional dialogue offers a clear path to healthy, open-hearted communication, the foundation of loving, responsive parenting.
