Extras is a great book and fantastic sequel to the Uglies series. Although it's set in the same world, this book is not told from Tally's point of view. In a way, that's kind of sad, because I've become emotionally invested in Tally's character. On the other hand, Tally does make an appearance (which is actually pretty substantial) and there is some very nice closure to her story which you don't get at the end of Specials. The other interesting thing about this book is its social commentary on today's obsession with the internet. It definitely delves into serious thinking about the benefits and risks of being constantly connected to everyone else (like twitter, facebook, and blogging *ahem*). This book also takes place in Japan, and I thought it was interesting to imagine how a different culture could change in the future. Are we all headed towards some sort of sameness because we're constantly connected? Or will we be able to keep our individual cultures? Lots of interesting questions to explore, and on top of all of that, this book is just plain good. Great characters, lots of exciting and interesting plot twists, and lots of fun. Great read!
