"Under the Dome" by Stephen King.
The last three books of the Dark Tower Series by Stephen King.
"The Haunted" by Jessica Verday
"Gone" by Michael Grant
and some others that I can't remember off the top of my head.
I think my favorite book of the year was "Gone" by Michael Grant. I just found the way that he built up the world without parents was very well done. I also fell in love with the build up of the conflict and how it came to a head. It seemed well paced and believe in context of the story.
