Hi there, FD -
If you have anxiety (and most of us do) - especially if you are prone to anxiety attacks - I highly recommend Hope & Help For Your Nerves by Dr. Claire Weekes. This was the second book I read, after The Divided Mind (my first and only Dr. Sarno book) and it helped me tremendously.
I have actually purchased several copies of The Mind Body Prescription (back pain was not my issue) but I keep giving them away. I buy used copies if I can :^)
I am currently reading, and am absolutely fascinated by, When The Body Says No by Dr. Gabor Mate. Dr. Mate explains the physiological changes that occur in our bodies when they are exposed to what he calls the "stress-disease connection" where the stress is caused by repressed emotions. He also proposes some pretty radical ideas about how most, if not all, of the auto-immune conditions are caused by this stress, along with many cancers, to say nothing of the conditions we already accept as TMS equivalents such as fibro, IBS, etc. I am finding this information to be very empowering, although I suppose others might find it scary! It's a totally different way of thinking for most people, that's for sure.
Steve O's book is a terrific encyclopedic roundup of TMS experience and information, 100% devoted to the theories of "the good doctor" (Sarno) as Steve calls him.
I purchased Dr. Sopher's book, but gave it to someone for her teenage daughter - I have to say, it was too simplistic for me, after I'd read TDM and done a couple of weeks of the Structured Ed Program on the wiki - but I think it would be an excellent book for a young adult to start with, and I'm not sorry that I was able to give it to someone.
Happy reading and recovery!
Jan
