Query: A how-to book that gives no information about MVPS

What a disappointment. As it turns out, this author has done many "how-to" books with little depth or understanding of the disease. To me, it was obvious that he knows little to nothing about MVPS. There are global statements with no medical references. I'm sorry I wasted my money. Disappointed reader.
