"Special Circumstances" - These words have sent chills down Tally's spine since her days as a rebellious Ugly. Back then Specials were a sinister rumour - frighteningly beautiful, dangerously strong, breathtakingly fast. Ordinary pretties might live their whole lives without meeting a Special. But Tally's never been ordinary...Now she's been turned into one of them: a superamped fighting machine, engineered to keep the Uglies down and the Pretties stupid. The strength, the speed, and the clarity and focus of her thinking feel better than anything Tally can remember...most of the time. One tiny corner of her heart still remembers something more. Still, it's easy to tune that out - until Tally's offered a chance to stamp out the rebels of the New Smoke permanently. It all comes down to one last choice: carry out the mission she's programmed to complete, or listen to that tiny, faint heartbeat telling her that something's wrong...Either way, Tally's world will never be the same.
