Query: not very good

it is not written in a very informative way, it is not a good book for people with friends who are sex addicts, it does not go into detail of the psycological aspects, or what friends can do to help. It did not explain enough for me to understand, tried to inform by describing cases of real people, but was all just blah blah blah. I wouldnt buy another book from this author. If anyone has read some really informative books on the subject please let me know the names and authors.
