Ages 15 and up 

Tally thought they were a rumor, but now she's one of them. A Special. A superamped fighting machine, engineered to keep the uglies down and the pretties stupid.
But maybe being perfectly programmed with strength and focus isn't better than anything she's ever known. Tally still has memories of something else.
But it's easy for her to tune that out - until she's offered a chance to stamp out the rebels of the New Smoke permanently. It all comes down to one last choice: listen to that tiny, faint heartbeat, or carry out the mission she's programmed to complete. Either way, Tally's world will never be the same.
