History Literature / InsideOut

''Inside Out'' is a YoungAdult book written by Maria V. Snyder.

Trella is a scrub of Inside, a low-class citizen whose sole expected duty is to scrub pipes in service to the Uppers of the society. And, for the most part, she does her job as all scrubs do.

But she's different in that she has a friend, Cog, and that she uses the pipes to sneak around and spy on Upper levels. And when Trella hears that the fabled Gateway to Outside may exist, she's enlisted to find evidence...and ends up kickstarting a revolution.

Its sequel is ''Outside In'', which takes place sometime after the events of the first book. The sequel deals with the ramifications of what Outside properly means...and that things aren't quite as they seem out there.

Not to be confused with the [[WesternAnimation/InsideOut Pixar film of the same name]]. Though oddly enough both feature [[NamesTheSame a character named Riley]].

* PopulationControl: The population is divided into two castes, the Uppers and the scrubs. Scrubs are encouraged to have as many children as possible and are denied birth control. Men and children who break the rules are executed, but fertile women who commit infractions become "breeders", kept chained down and constantly pregnant until their bodies give out from the strain. Uppers, on the other hand, are allowed one child per couple. If there's an accident with their birth control, the extra child is dyed to look like the scrubs' ethnicity and given to a scrub foster mother. The overlords use this to foster class division, telling the scrubs that the Uppers are spoiled rotten and telling the Uppers that the scrubs are too lazy and selfish to use birth control despite their overpopulation.
