scbwi.org, click on International Conferences. It's the summer one in L.A. ... for SCBWI members, it's $475 for early registration, and it's a full four-day conference.
I went last year, and it was awesome! I was at that place where I had just finished my manuscript and was finishing revisions, getting ready to start querying. I DID do the manuscript critique last year, which was mind-blowing. I got Anica Rissi at Simon Pulse. I would highly recommend it. I'm not doing it this year though. I'm working with an agent, so I feel like I'm getting the professional feedback I got from the critique last year already. I am excited about the YA Voice Intensive, though. I'm hoping to finish these stupid revisions (same book I went to SCBWI with last year) so I can start on my new project; that's the book I want to focus on in the voice class.
If anybody reading this needs a roommate: I'm super introverted in person and can sleep through anything. I don't smoke. I own many animals but don't plan on bringing them with me (although some of their fur might hide in my suitcase).
Well, full disclosure, I don't have the agent YET. I have to successfully complete these revisions, submit the new manuscript, and have him think I made good enough progress to want to keep working with me! It's how he works. I agree to work with him exclusively, he spends time drafting an editorial letter, and I revise based on his notes. I really hope I don't blow it, or I'll be back to square one. And that square, the querying-and-looking-for-an-agent square, well ... it's hard! But at least I'll be going out there again with a stronger manuscript.
