I was so excited to read Extras because I have loved Westerfeld’s series. I just couldn’t go out and buy the hardcover, so I waited until my library bought it and stole it home for a night. And, it didn’t let me down. Within a day, I had read it cover to cover and gobbled it up. The Japanese-themed world where Aya and Hiro and the others lived was genius and successfully played out in this manga and anime-crazed kid world. Beautifully done!
