I don't get terribly excited about those book tournament things we've been seeing the last few years because the titles considered are usually that season's Big Name Books. We've already heard a lot about them. We know everyone loves them. Do we really care which ones are loved more? I'm guessing the answer to that must be yes, though for me, not so much.
However, Liz at Tea Cozy posted recently about a tournament for books that didn't get the band wagon treatment the year they were released. Nerds Heart YA is a tournament for books that you might not have heard of. A wonderful idea to help get attention for titles that really need it.
