Dana,
Please keep us informed on what you hear from her. I sent a query to her after she returned from the AWP Conference (where I met her) in February. Still no word. One thing she said at the conference was that they have a very strong spam filter. If you have not heard back from them at all, you should re-query.
While I'm here, I thought I'd pass on some other interesting things I heard from this agent panel:
1. Unless the agent says, "no response means no," you should re-query if you hear nothing.
2. Mention that this is a multiple submission in your query. (That was a surprise to me, since I thought it most agents assume it's a multiple sub.)
3. If you have another book in progress, mention it briefly--a one-sentence description is fine. According to two of the agents on the panel, they want to know that you're not a one-book wonder, that you are in this as a career, not a hobby. This one was a surprise to me too because I've always heard you query only one book at a time.
4. All of them said that the best place to find an agent was at a conference, that the face-to-face contact can move you up the ladder in terms of response. It doesn't guarantee representation, but it does add another level of interest, especially if you made a good impression. Even you don't get the opportunity to talk to the agent at a conference, you should still mention any panel discussions or talks they gave. It shows that you have a professional interest in learning how the industry works.
Just a few thoughts...Keep us posted about PW.
