I have a list of books that I've read this year and some months have a lot of books and some months have only one. It all has to do with the size and scope of the book and how much time I can devote to it. I finished ten books in January but only one each in March, April and May. I think June and July will end up one book months as well. The January books were a couple of "light reading" series but since then I've been reading either longer books or "classics".
I've been trying to slow down my reading -- I generally read a book through very quickly, trying to get the high points and past the any suspense or hidden surprises. Then, if I liked the book, I'll read it again more thoroughly and take the time to absorb all the other details.
Now it seems to be taking me longer to read books since the ebooks are forcing me to read carefully the first time through; I can't just flip pages (easily) to read bits at the end before I get there. (Books go faster when you know what's coming.) It's both frustrating and amazing at the same time -- I mean, to actually be surprised when something happens because I didn't know it was coming? That used to never happen to me!
