When my first book was published, I naively wrote away to a bunch of famous writers, whom I admired, asking them to blurb my book. I was pretty dumb and didn't know you had to be some one's friend, writing student, or lover to get a few words for the back of your book.
Here is a rejection from Dorothy Allison in 1996. It says: "Dear Writer, Rejected: Everyone is right--I don't read manuscripts for quotes anymore. Had to stop it cold the month I got more than a hundred. But I wish you well, and I'm glad you found your voice. Hope [name of publishing company] treats you good, and we get a chance to talk sometime." For years after I received this note, I saw Allison's name on what seemed like the back of EVERYONE'S book. But whatever. A girl has to have boundaries. I thought it was nice that she bothered to write back and send me her autograph.
On the other hand, so much for the solidarity of the sisterhood and lending a hand to the little-guy.
