I've only read one, i think its called Building the Bonds of Attachment, or something similar, i think i read the older version, the newer one changed the therapy a bit from what i understand....but it was written almost like a novel, but gives a good picture of what therapy for RAD might look like, and the causes, etc. I really liked it. It was even enough to follow that i was able to read of it to my son (11 yrs old) so that he would have a better understanding of some of the issues that a foster or adopted child might face. I havent read much else by him, but i really like him!
