I just want to say that I signed with Katelyn earlier this year. The project she signed me for just sold, and in the interim, she sold another project of mine in 2 weeks to a "Big Five". Katelyn and her team are fabulous and answer all of my many newbie questions within a reasonable amount of time. I never feel out of the loop or ignored and dispensable as I had with previous agents. If you doubt querying her, don't. All of her clients will tell you the same. She is my game-changer. Don't let their lack of a website deter you (it's been like that for years as they turned new authors into bestselling ones).

KellyE - I found info on Publisher's Marketplace. When I queried her last it said query + 50 pages.

With the website down, does anyone know what they want for a query? ie just the query? query and synopsis? first 3 chapters? Many thanks!

"Please send your query letter to and attach the first 50 pages (fiction) or proposal (non-fiction) as a .doc file."

Do you query using the form on their website? What should I include for the file attachment? (I can't seem to find any information on how to submit.)
