Shatter City

EVEN WHEN YOU'RE PRETENDING TO BE SOMEONE ELSE, YOU CAN'T ESCAPE WHO YOU ARE. When the world sees Frey, they think they see her twin sister, Rafi. Frey was raised to be Rafi's double, and now she's taken on the role...without anyone else knowing. Her goal? To destroy the forces that created her. But with the world watching and a rebellion rising, Frey is forced into a detour. Suddenly, she is stranded on her own in Paz, a city where many of the citizens attempt to regulate their emotions through an interface on their arms. Paz is an easy place to get lost...and also an easy place to lose yourself. As the city comes under a catastrophic attack, Frey must leave the shadows and enter the chaos of warfare--because there is no other way for her to find her missing sister...and have her revenge against her murderous father. This description comes from the publisher. Shatter City is the second book in the Imposters series, the first of which is Imposters; this series is the sequel series to the Uglies series, the first of which is Uglies.
