A friend of mine is represented by Andrew Stuart. Last time I checked, I think he liked him fine, if not overly much. This friend recommended a novel of mine to Andrew, who asked me to email the full ms to him last April 2007. I never heard back from him.
In June '07 I saw Andrew at a party thrown by my friend (his client) and mentioned that I had sent the ms at his request. He had no memory of it and asked me to send it again. I did so. I have never heard another word from him. Nada--not in response to a polite email reminding him of our personal meeting and his request to see my novel--nothing at all.
So--I hate to to write this so often about agents--but my experience with him was very far from inspiring. (And not that this should ideally matter in terms of agent responses, but I've published a novel with a major press for which I appeared, among other places, on C-SPAN and which was blurbed by two very very major writers and so, combined with a client recommendation, my ms isn't exactly coming out of nowhere.)
But, yeah, I look at the record of my submissions and I see that under the category of "MANUSCRIPT ABYSS" (ie, submissions about which I've never managed to get a word of response) is "Emailed full ms. to Andrew Stuart (X’s agent): 4.23.07" So I sure can't recommend him.
