Launch date for Eva Beale's Grey Gardens book: September?

Word is quietly slipping out that Mrs. Bouvier Beale Jr.'s upcoming book on Little Edie's youth will be launched at Grey Gardens this September. Eva was in town on Thursday finalizing plans with her publisher and has begun asking family and friends to hold open a few dates.

We first heard about Eva's book from writer Gail Sheehy, who interviewed Eva, and who is working on a book of her own about the Beales.
