It has been three hundred years since humanity attempted interdimensional travel; three hundred years since the project went horribly wrong and a permanent rift was ripped open between another dimension and our own. Having fallen to the savage and staggering force of the MPs -- formless, ravenous blobs that feed on sentient life forms -- humanity has lived on within the hastily-erected walls of Atlas, humanity's final refuge. Society has changed to fit the needs of the human species, placing stock in a new system of Heirarchy that keeps the city grounded and goal-focused. Yona Smith is a Laborer at the very bottom of the food chain, tasked with the upkeep of the Wall -- Atlas' only barrier between humans and the MPs. One day her peaceful life is ripped away along with any illusions of safety. All is not well within Atlas: the higher up suck precious resources dry while those lower toil unknowingly, and the MPs are getting...smarter.Unforseen catastrophe is on the horizon, and Yona finds herself in a position she never would have imagined.
