Week 25 but only 19 books

I have kinda stalled on the whole "1 book a week" thing. I have only read 19 books and we are on 25 week. I have however worked out that if I read 2 books a week for the next 6 weeks, I'll manage to catch up again. Looks like I'll be hitting the smaller (~300 page) books in my collection and of course making time to actually read them.
