Well, Gary just told me in Atlanta that he really loved my book, Looking Through the Eyes of Trauma and Dissociation: An Illustrated Guide for EMDR Therapists and Clients. I bet he'll mention it.
You might see what the people at SIDRAN books are currently recommending - they are an organization by and for dissociative folks, and they have extensive reading there.
www.sidran.org I think is their website.
