NPR is polling for best YA novels; leave your five top choices in comments (annoying login required; it's relatively quick and painless).
You can list an entire series as one choice (ie, Hunger Games trilogy), or just a single title from a series (Mockingjay).
I "voted" for Chaos Walking trilogy by Patrick Ness, My Most Excellent Year by Steve Kluger, Jellicoe Road by Melina Marchetta, I am the Messenger by Markus Zusak, and Hold Me Closer, Necromancer by Lish McBride. This is almost a random selection of the recent YA titles I love best; I couldn't pick an absolute top 5 of all time.
I think it would be awesome to do a bit of culture jamming and push some really fantastic titles through the poll, not just the most popular titles (ie, Twilight, Hunger Games). Chaos Walking would be my pick for culture-jamming title of choice, followed by I am the Messenger (based on personal preference and literary quality). But I'm curious to see the results of this survey, and I think everyone with an intelligent, informed opinion should vote.
