I hate being a fast reader--since Christmas, I've read The Hunger Games trilogy and Matched by Ally Condie.
I really enjoyed The Hunger Games, and I'm glad I kept myself unspoiled for them. While I thought they were good, I couldn't help thinking that it was like The Running Man and The Long Walk got mixed in a blender, and Hunger Games was the result. Mockingjay was my least favorite of the trilogy.
I liked Matched as well, although it seemed very similar to The Giver. I tend to like stories set in weird futuristic societies, so it was a fun read for me.
