I don't have a favorite character to use for the letter Y, so I searched for Y characters in books that I've yet to read. Tally Youngblood seems like an interesting choice so I put this book on my TBR list.
Here's the blurb for Uglies by Scott Westerfeld.
Tally Youngblood is about to turn sixteen, and she can't wait for the operation that turns everyone from a repellent ugly into a stunningly attractive pretty and catapults you into a high-tech paradise where your only job is to party. But new friend Shay would rather hoverboard to "the Smoke" and be free. Tally learns about a whole new side of the pretty world and it isn't very pretty. The "Special Circumstances" authority Dr Cable offers Tally the worst choice she can imagine: find her friend and turn her in, or never turn pretty at all. The choice Tally makes changes her world forever
