I am an avid reader of YA fiction. As a school librarian I have to be.
I am currently reading the 2009 Rebecca Caudill list. (an Illinois state contest where they give you 20 books, you read them all and then vote on the best - open to everyone in IL - many states have similar contests.)
I'd thought I give you a couple of recent releases that are fantastic
The invention of Hugo Carbet - part graphic novel, part traditional, totally fantastic
The Twilight Series - Twilight, New Moon, Eclipse, Breaking Dawn - vampire/werewolves/human teenager love triangles
The Lightning Thief - Rick Riordan
Maximum Ride - James Patterson
Gossamer - Lois Lowrey
Airborn - Kenneth Oppel
Marked - PC Cast
Extras - Scott Westerfield - not the first in the series, but the first that deals with not humans.
