Hmm...The Iron King, The Maze Runner trilogy, Scars, and Unwind.
STRANGE ANGELS series by Lili St. Crow if you're into the supernatural; LEVIATHAN TRILOGY by Scott Westerfeld if you like steampunk.<br />
That's the only ones I know.
Jodi Picoult :) All time favorite
The Thief of Time - Terry Pratchett
Anything by Pratchett!
