One of my top 10 favorite MG reads last year was Matt Myklusch's Jack Blank and The Imagine Nation. You can read my 5 star review for the book here. I really liked the cover for book, but when I visited the Simon and Schuster booth at TLA, I was told the book received a make over with a new cover and title. Let me say, this is an awesome new cover!
If you're looking for a fantastic series/book to get any young boy (and girl), I highly recommend picking this book up!! I'm looking forward to the release of it's sequel, The Secret War when it's out in August.
