'Harry Potter' and 'Hunger Games' Voted Best YA Novels, 'Twilight' Nowhere in Sight

"Harry Potter" and "The Hunger Games": Which is the best young adult book series of all time? When you have a question like that, there's only one thing to do: start a poll.

That's what NPR did, but they expanded the pool to just about every young adult novel or book series ever, allowing fans to attempt to vote their favorite into the top spot. The results are not terribly surprising, as the "Harry Potter" series took #1, with "The Hunger Games" right behind it in second place.

What is interesting is that the "Twilight" series is nowhere near the top ten, despite its huge popularity. The series came in 27th place, putting it somewhere in between Flowers for Algernon and The Sisterhood of the Traveling Pants. It's sort of a shame that Twilight beat the likes of Howl's Moving Castle, but hey, them's the breaks.

The top 20 on the list is a veritable who's who of big-time movie adaptations. Of course we all know about the success of the "Harry Potter" movies, and we've seen what the "Hunger Games" series will likely be (read: huge), but there's even more past those two. From older adaptations like "The Princess Bride" and "The Hitchhiker's Guide to the Galaxy" to "The Perks of Being a Wallflower" and the "Divergent" series (to which Summit bought the rights last year), it's clear that the way to get your book made into a movie is to make it for a young adult audience.
