Bearing in mind that Dr. Callahan made his discovery over 20 years ago this book has been a long time in coming! However, I expect the majority of readers (and users) will not be disappointed. Concise, well written and more accessible to the general reader than his earlier and more theoretical book "Stop the Nightmares of Trauma", Dr. Callahan details his work from its tentative beginnings to some astounding recent findings. Also well presented are step-by-step treatment procedures that Dr. Callahan says will lead to a cure in 75-80% of those who use them correctly. Of course, this will be a grave disappointment for the 20-25% on whom these basic procedures will fail to work. Nevertheless, Dr. Callahan even throws out a lifeline for these people, with a section on troubleshooting the treatments and an invitation for those with more complex problems to contact him directly for advice. I expect few people will do this though - it's so much easier to be satisfied with failure and blame the "driver" than pick oneself up from despair and grab an opportunity that's too good to miss. The more curious and scientifically minded would do well to buy "Stop the Nightmares of Trauma" to get the bigger picture.
