Frey's return to the city of her birth isn't going to be an easy one. She and her love Col must surge on new faces and bodies in order to infiltrate Shreve by dropping from the sky and landing undetected.

Frey's sister Rafi -- no longer a twin in features, but still a twin by birth -- is the wild card. Are the sisters on the same side . . . or are they playing to their own agendas? If their father is deposed from Shreve, who will take control? And what other forces may be waiting in the wings?

Mirror's Edge is another brilliant blockbuster from one of the greatest speculative writers YA fiction has ever seen, set within the world of Uglies . . . and about to converge with Uglies in a spectacular way.
