Alcoholism Recovery & Treatment

I have been involved with a company called sober nexus that offers free online information for those seeking a drug rehab or substance abuse treatment center. I’m wondering what resources OTHER people use when seeking drug or alcohol treatment for addiction and alcoholism?

Mental illness and alcohol are factors; also last contact included some violence. Children are not allowed by father to discuss it openly, except to demonize mother. Counseling currently not an option. Looking for an age appropriate book, perhaps, that deals with loss – specifically loss by choice. A parent resource would be good also. I am aunt of children; concerned about possible feelings of misplaced guilt, anger, loneliness, love.
