I found this at a used book store for around 75 cents. I think this was meant to used by students studying psychology and mental disorders. I picked up this book out of pure curiosity and I really enjoyed reading it. It was easy to read and follow even though I have never studied psychology formally and had a large range of case studies that were all equally interesting. I also like the format of the book and how there is dialogue to break up the monotony of information being given.
