In a world constructed on logic, a single emotion can bring everything crashing down.
Human beings have evolved beyond emotions. Envy, greed, and hatred cease to exist. Behind the government, the System weighs every decision to secure an efficient, long-lasting society. Anything without value--the weak, the disabled, the Emotionals--faces termination. There is no crime. There is no violence. There is no war.
Everything is perfect.
For the past sixteen years, Penny and her family have eluded the System, hiding amongst the Rationals, learning to emulate their ways. But when her sister fails her year five test and exposes the family secret, Penny abandons her family and takes refuge in the hills outside Region 7.
The hills aren't empty. There are others like her. Hundreds of them. Their leader, Professor Hume, has a plan to infiltrate the Rational government--a plan sixteen years in the making. Given a stolen identity and thrust into a position of power, Penny must use everything she learned from her parents to persuade a movement that will change the world forever.
Yet the more she learns about Professor Hume, about the origin of the Rationals, about the mysterious boy Charles, about herself, the more the question burns in her mind: what if she's helping the wrong people?
