I first heard of this book from a friend who had to read it for a class she was taking. once i started it, i was hooked. Scott Westerfeld has written an entirely unique future for our planet, one that is enticing to think about, exciting, while also scary. it really makes you think about how we see ourselves and others around us. for a very quick summary that hopefully wont give too much away; Tally is a 15 year old girl, which means she is still an Ugly. she lives apart from the older Pretties, in a dorm across the river. in her world, when you turn 16, you get an operation that completly changes you. not only your outside, but also the way you think and act. while she waits impatiently for her operation, she meets shay, who is unusual in that she doesn't want the operation. in fact, she is desperate to get out of it. so when shay goes missing one night, Tally is given the task of finding her, or else she will never be Pretty.
