Query: I returned this book to Amazon

I began to read it and didn't like it at all. I skimmed through the rest of it and found it a terrible bore, badly written, and not particularly helpful. I agreed with another reviewer, who stated that implementing the strategies outlined in the book would actually make a bad situation even worse. We decided to go with the Collaborative Problem-Solving Approach outlined in The Explosive Child by Dr. Greene, and so far we have been very pleased with the results, especially in the home environment.
