For those of you who got a request from Mary, did you get a confirmation when you sent the requested materials?
03/22/2023 05:42 PM
I submitted one attachment with the first and last pages, and the synopsis all in one document.

For those of you who received a request, how did you submit the first and last 25 pages + synopsis? Did you put all of those into one file?

4/5/22- EQ & first 3 pages

4/5/22 - Partial Request for first 25 & last 25 pages + synopsis (submitted same day)

4/9/22 - Full request! Crossing my fingers for this one.

4/12/22 - Received an offer of rep!! Mary is passionate about my manuscript, prompt in her correspondence, and easy to talk to. She seems absolutely lovely!

4/25/22 - Accepted Mary’s offer of rep! I can’t wait to work with her as I navigate the road to publication! :)

Nudge: 11/29/21 (she told me to nudge her at the end of November if I hadn't heard from her)

YA Fantasy 95,000 words. From the looks of the comments here, she usually sticks to Children's and MG, but if she likes the query enough, she'll ask to see more. Fingers crossed!

PB 500 words. Website does not specify how long to wait before assuming it's a pass, but given how quickly she tends to respond when interested, I think it's safe to close this out.

FYI: This agent is big on picture books. She had a few MG sales. The only YA sale she made was in 2011.
