20. The Hunger Games by Suzanne Collins 21. Catching Fire by Suzanne Collins 22. Mockingjay by Suzanne Collins
These were a very easy read for me, and quite interesting. My MIL had asked if it would be appropriate for my 9yo nephew, but at the time I'd only seen the movie. I can say now that it's not quite appropriate, though it does depend on the kid. It's a bit darker than most YA novels, especially towards the end.
"You need me. You wouldn't be much of a hero without a villain. And you do love being the hero, don't you. The cheering children, the swooning women, you love it so much, it's made you my most reliable accomplice." -- Lex Luthor to Superman, Question Authority, Justice League Unlimited
