I think I'm behind in all of those recent books that are out.  I've read almost all of the books of the popular series, but I forget easily, and now that new books are out, like the most recent of Artemis Foul, etc..... I don't feel like reading the whole series again

I just like reading a whole series at once, not reading one book, forgetting it, waiting for the next one to come out, and having to read the first one again!
