Got a very nice rejection letter from Erin (I'm guessing her assistant) on Johanna's behalf saying she can only take projects that are a perfect fit for her list so keep trying :)

She was super nice. She was the first to ask for a partial manuscript but at the end passed.

Notified her that I'd already accepted an offer of representation from another agent (I had forgotten to notify Johanna); her office seems to be slow to respond, so if you get an offer from another agent, definitely let her know and give her a chance to show her interest!!
