I'm revising a book that I wrote in 2005. Editors liked it but didn't love it. It was missing something. So when I went back to it last month, I had to reread the whole thing because I couldn't remember what happened through most of it. My three first readers could (a good sign) but I couldn't sum up anything but characters and a few key scenes.

But I also have a terrible active memory for books period. I enjoy them and absorb them. Can't call anything up unless prompted. Give me a test on a book and I'll ace it. Otherwise I've got nothing.
