Stardust movie, because it's really quite good, but at the same time, I think the book edges it out.
Anyways, as the title of this post says, the next book on my reading list is Lev Grossman's The Magicians.
TV adaption is set to premiere this month and I want to read the book before hand. That's not the sole or even primary reason, however. I've had this book for several years now (either a Goodwill or library book sale find), which in of itself is reason enough, but also I've heard nothing but good things about The Magicians, so it's worth checking out at least.
