Twins. Liars. Rebels.

Frey was raised to take a bullet.

She's the body double for her twin sister Rafia - the precious first daughter of Shreve - and her existence is a closely guarded secret. So while Rafi was schooled to be the perfect heir, Frey was trained to be the ultimate weapon. Her purpose: to protect her sister.

When their father sends Frey in Rafi's place as collateral in a precarious deal, she must become the perfect impostor. But Col Palafox, the son of a rival leader, is getting close enough to spot the killer inside her. As layers of deceit peel away, can Frey become her own person, and risk everything in a rebellion?

As the deal falls apart, Frey must decide: can she trust Col with the truth? In a life built on lies, can she trust anyone?

Compulsively readable, set in the Uglies universe, full of twists and turns, rebellion and intrigue, Impostors is a thrilling read from bestselling author Scott Westerfeld.
