Fire by Kristen Cashore: Book Companion to Graceling!

I can't wait to get my hands on this second book to Graceling! It seems Kristin is making the books into a trilogy called The Seven Kingdoms Trilogy. Makes sense and all to call it that! I wonder if we'll see more of Po or Katsa??? I hope so! Hopefully, I will find Fire at the library! Can't wait! :)
