14 hours, but I fixed lunch and dinner in that time. And I had to read a couple of the earlier chapters (or parts of them) twice -- like when the side car fell off the motorcycle. For some reason that one really threw me for a loop. Hedwig falling and then the sidcar falling off. I just had to read it again.

I haven't started reading it a second time yet because I'd started another book that I hadn't finished when stopped to read HP7. I'll finish it and go back. I may wait until school starts.
