This book is not an easy read, it is quite academic. It is, however, worth persisting with for anyone who feels they, or someone they know, has become addicted to cyber sex. The book would make very good reading for someone working in the mental health field with people who have any form of sexually addiction. It explains how the problems manifest themselves and how it deal with it. There are several self diagnosis tools, some of which are a little uncomfortable to answer, that help to identify the addiction.
