Anyway, on to the goods. My top
5. Variant by Robison Wells
Slow first half, but non-stop second half.
4. The Knife of Never Letting Go by Patrick Ness
I've never read anything like this. (But it is very, very violent)
3. The Maze Runner series by James Dashner
The second book was the best, but the ending makes for good discussion. (Also very violent)
2. Possession by Elana Johnson
I really enjoyed reading this book, and the ending made me love it.
1.5 Delirium by Lauren Oliver
I was afraid it would be a retread of other dystopian books, but holy moley it was just really good.
1. Matched by Ally Condie
Even if Crossed left me disappointed, it doesn't take away from how incredibly well-written Matched was.
ETA: D'oh! How could I have forgotten Delirium? It's now in it's rightful spot at 1.5
