My Favorite Series

Hello! I just had this urge to parade around my favorite books/book series, and I thought to myself: Why not make a blog post about it? I'm sure it's not that hard to figure out, but anyways...
I won't leave an explanation as to why it's my favorite series exactly, because I think things like these are totally subjective. Of course there are certain arguments that made me like the series, but that's not debatable, so it doesn't matter anyway.
