She's asking for the first three chapters or 50 pages, whichever comes first.
Has anyone heard back from her?
With this agent - romance or commercial fiction or anything else - appears to receive the same treatment - silence. Considering that 50-pages will run you into some postage - and postage these days is nothing to sneeze at, I'd spend my money better way. There may be writers out there who actually received a reply from this agent, asking to see more or rejection, but general trend is silence. A while back I sent an e-mail query and like someone else said, it wasn't rejected but neither was it acknowledged.
In my experience, any agent asking to see first 3 chapters along with a query should be sent only a query. 1-page, first class postage and invitation to respond, reject or ask for more, via e-mail - which mens include your e-mail address. Don't bother including SASE because in 95% it will not be used to send you rejection or acceptance and it's a waste of a stamp. Mailing is expensive these days and rates keep rising. 50-pages, even if you persuade the Post Office that it's <printed material> and they let you use <business class> will still run you into fair expense.
I find that if you send a query letter and include your e-mail, in more than 50% cases the agent will use the e-mail to reply - reject or invite to see more. And then they'll tell you how they want to see it - as hardcopy or e-mail attachment.
Very recently I received e-mail from Clarissa Rappoport-Hankins, of Anderson Literary Management, LLC - queried her months ago via e-mail. She states:
"I suspect that this letter comes to you atrociously late, and for that I am very sorry. We have been in the process of reorganizing here at Anderson Literary, and I found the first 50 pages of your manuscript XYZ. If it isn't too late, I'd like to take a look at the full manuscript (you can just email it to me at this address).Again, we are terribly sorry for the delay!
Now, I am very weary of e-mailing a 354-page manuscript in Rtf by e-mail. I sent her 50 hardcopy pages - and I doubt I will be sending the whole m-script by e-mail. I'll do that only to an agent who has signed-me-on. I am perfectly willing to send her the m-script as a hardcopy, but e-mailing the whole novel...nah. I'm not paranoid but I am somewhat leery about this practice of e-mailing whole manuscript as an Rtf file on spec.
You see, I have this annoying experience with Manus Literary in Palo Alto. Three years ago, they had an agent with them who requested first 3 chapters of another manuscript. She liked those and asked for 6 more...and so on, piecemeal until she read the whole thing and liked it well enough...if I did some re-writes. She never said the agency would offer me representation - she just liked the novel. We corresponded back and forth about re-writes and I was just wrapping my mind around how to do it when her e-mails stopped. I emailed Jandy Nelson - who's been with the agency for a long time. She replied that the said intern/agent was no longer with the agency and she took all her work files with her. So she didn't have any knowledge of my work that the agent discussed with me. And no, she wasn't interested in representing me...my work unseen.
So that sort of made me shy away from any agency that requests the whole m-script as Rtf file. Hardcopy is cumbersome and generally I'm an environmentalist, but hardcopy can also be recycled. Files that leave with the intern-agent-assistant...are not that assuredly recycled. It was one of the reasons why I opted to publish that particular novel as e-book. Just sharing experience. Regards.
