It's not as impressive, but I'm currently working through the four-book box set collection I got of Calvin and Hobbes. I'm on book 2, but there are so many strips it feels like I haven't even made a dent x___x
I'm also trying to get myself to read Game of Thrones. It's very difficult for me to just sit down and read things (especially after leaving high school) so I'm trying to get myself back into reading regularly.

But they're not "sequels", they're all books that are a part of one whole trilogy > < It's not like Suzanne Collins was like "OH THE HUNGER GAMES WAS A HIT, BETTER RELEASE MORE BOOKS" (that would be like calling The Two Towers from Lord of the Rings a "sequel" and not reading it because of that). The whole trilogy was out before they even became popular enough to get their own movie adaptions.
Please, please, please read Catching Fire (Book 2). It's so well done, I actually like it more than the first book. Mockingjay (Book 3) is okay, I don't really prefer it, but it wraps up the story at least.
But read Catching Fire. It's amazing ; ;
