I know exactly the feeling you're referencing, and I felt the same way with The Hunger Games. While I do love the classics dearly, they tend not to "suck me in" as some of these other, more contemporary young adult books do. With that said, the last book(s) that did that for me was The Maze Runner Trilogy. It's dystopian and similar to The Hunger Games in some ways, but also very different. I highly recommend it.
I think it is important that we find books like these that we can reccommend to our students. Yes, the classics are so important, but they will be exposed to the classics with our curriculum and most likely won't reach all students. If we can get excited about these other books and pass them on to students, and then have THEM pass them on to each other, I think we would be doing a wonderful thing.
