I hate it when I see an agent or editor closing to queries but, if it has to happen, making it temporary isn’t so bad especially if someone is getting caught up.
Molly Ker Hawn just announced on the Bent Agency Blog that she is closed to queries until September 1, 2015 so that she can get caught up. If your query reached her before July 9, 2015, she will read your query. If it arrived after that you will have to resend in September.
Look at this as a good thing — you have almost a month and a half to polish your manuscript and get it ready to go. So get to work and good luck!
