I just want to say that I signed with Katelyn earlier this year. The project she signed me for just went to acquisitions (editors respond very well and more or less quickly with her), and 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!

From the agency's Publisher's Marketplace page:
"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.)
