Closed to queries.

Yeah, I figured I would have to write her off.

@KAusten Hmmm, then at this point I would definitely concentrate my efforts on other agents. Truly, some agents, like Roberta, seem great but when they say they have a "full client list", keep closing themselves to queries, and they're lagging in responding to submissions then I take it that they just aren't looking for any new clients right now. It's frustrating, I know. Anytime I get a query that manages to make it to a submission of a partial or full manuscript, I get excited. It's a real downer when the waiting drags on forever. But it just sounds like Roberta has her hands full right now. Hopefully other agents reply to you soon. :)

Also, keep in mind that she's a working author. She could have her own author deadlines that she's dealing with so that could have an influence on this too.

Thanks Shellyboo. When I saw she responded to your partial, I decided to nudge her (now over a month). Haven't heard anything.
Her website says they are not considering any new material in any genre, unless a NY author seeking new rep, and are closed to submissions until August 1st. At least it's a date for further query consideration for those who want to query her later.

She responded to mine, KAusten, and we had a query date at around the same time. Maybe she's still considering your partial submission. She noted in the rejection that she sent me a couple of weeks ago that she's really backlogged and is taking longer to respond. You can try nudging her, but I suspect she's one of those agents that's just going to take awhile... probably a great while. If you have any other agents that you're querying or waiting to hear back from, I'd focus on them instead. I've got a few myself that I emotionally put on the backburner because they're taking a looooooong time to respond compared to others.
