Extras by Scott Westerfeld fits into the Juvenile Science Fiction genre. It was first published in 2007 and is recommended for people age 14 and up. Summary and Review: Like many of you I was surprised by this forth volume in the Uglies trilogy that was dedicated "to everyone who wrote to me to reveal the secret definition of the word 'trilogy'". It's been over three years since the cure for the brain lesions was released and the world is slowly regaining what it has lost. Unlike the first three books we are guided through this gripping adventure by Aya Fuse a fifteen-year-old Japanese girl whose one ambition in life is to be popular by "kicking" an interesting story about something important. In a world were popularity buys you everything including the best house, clothes, and friends Aya must do something great to change her mediocre life. In her search for this amazing story Aya meets up with the Sly Girls. These seemingly ordinary girls live on the wild side by riding on top of a super fast mag-lev train while trying to stay away from the kickers. Aya is forced to sacrifice her hovercam Moggle to be a part of their clique so she can gain access to their story but later rescues Moggle and uses him to unlock the greatest story every kicked. The one problem is that she got it all wrong. She has some help getting it right from her famous brother Hiro, her tech friend Ren, her boyfriend Frizz, the always-helpful David, and three of your favorite cutters and mine, Shay, Fausto, Tally. These eight people discover the truth behind the metal shortage and the inhuman "freaks" while once again trying to save themselves and the world from destruction. Extras is an interesting commentary on a world not far from our own where popularity is literally money and people must discover what matters most to them and what they are willing to do to overcome life as an extra. Westerfeld is spellbinding and awe-inspiring as he takes a different angle in this adventurous book with a hint of love story.
