When most people think of YA, they think of those mass-marketed series, turned movie franchise. Popular series have put YA on the mainstream map, so we're talking about the series we love and the ones we wish didn't exist and what the obsession is doing to the genre.
As always, tell us your favorite series so we can binge-read them over the weekend.
