Frey and Rafi are inseparable . . . two edges of the same knife. But only one of them is ever seen in public.
Frey is Rafi's twin sister-and her body double. Their powerful father has many enemies, and the world has grown dangerous as the old order falls apart. So while Rafi was raised to be the perfect daughter, Frey has been taught to kill. Her only purpose is to protect her sister, to sacrifice herself for Rafi if she must.
When her father sends Frey in Rafi's place as collateral in a precarious deal, she becomes the perfect impostor. But Col, the son of a rival leader, is getting close enough to spot the killer inside her . . . .
Set in the futuristic world of Westerfeld's Uglies books, this action-packed series starter barely pauses to take a breath. Frey and Rafi are 16-year-old twin sisters, but the people of Shreve don't know that. Rafi is the self-possessed face of Shreve, the city their father rules with an iron fist, electronically tracking the citizens' every move. Trained as an assassin, Frey is a secret who exists only as her sister's body double. After Frey, posing as her sister, is sent to the rival City of Victoria to help negotiate for much-needed steel, she joins a group of rebels to take down her father and prevent all-out war. In narrator Frey, Westerfeld presents a strong, complex heroine who learns to be her own person, not just a carbon copy. Themes such as environmental conservation and individual freedom deepen the story right up to its explosive finale, which will leave readers looking forward to the next installment. Ages 12 up.
