Update: I've had a very perplexing experience with this agency. The acquisitions intern, Biz, asked me for my partial and full back in May. By late August, I still hadn't had a response and, having done some major revisions, asked whether they would be interested in seeing the updated manuscript. I was told by Biz that my manuscript was going through a second round of readers, but to send through the new version anyway. About a month later, I got another email requesting a headshot and info on my platform as an author. After sending those through, I was informed that two other "agency fellows" had enjoyed my manuscript, but thought that it could benefit from some editing. Biz said she would be happy to help me with these edits herself, and I agreed to this. A few days later, Biz told me she was meeting with Carolyn Jenks to discuss the manuscript's potential. This morning, I received a rejection saying that Carolyn didn't think my story was "right for the agency".
I found this whole process pretty confusing, and was disappointed by the form rejection, after going through so many stages (including the preliminary offer of editing help). I couldn't help getting my hopes up a bit, since no other agency has put me through such a process. I was also left wondering about who the other agency fellows were and how much Carolyn knew about my manuscript, before they brought it to her, after all this time.
I would not not recommend this agency, but I would advise people not to get their hopes up, as I did. Their selection process seemed a bit unorthodox, and perhaps not as efficient as it could have been.
