Pulse Point is set in a future where the climate has made the world inhospitable to humans. In order to survive, people live in self-sustaining domed cities. The City that Kaia and her family live in is run by Overseers, guards that ensure all the Citizens follow the guidelines so the City can maintain its “Energy In = Energy Out” policy. Citizens are only allowed to use the energy they create. Energy production is calculated and displayed on their pulse point, a transmitter embedded in a person’s finger. When a Citizen is no longer able to produce energy, they are Balanced, or killed.
