There are a lot of great resources out there for parents of children with Reactive Attachment Disorder. Check out the board on at this site for issues with older children, moderated by Dr. Art. He was my sons attachment therapist. My son has resolved his attachment disorder.
Nancy Thomas's stuff can be found at
www.nancythomasparenting.com. Her stuff is mainly on parenting techniques.
Dr. Art has good information on his website, plus recommendations on books, etc. Check out:
www.Center4FamilyDevelop.com. My son's story is in the section labeled "hope".
RAD is definately not a blame the child diagnosis. Maybe blame the circumstances, but not the child. The child and their adoptive/ foster families are the victims here. But there is hope and with the right therapy families can heal. The key is a properly trained therapist. Check
