The Fever. A sickness to destroy the world. Worse than the Black Death, worse than tuberculosis. Within the Box, paradise is free. Free of plague, free of conflict. For Louise, it is all she's ever known. At 23, an unimportant mail carrier like her has no life outside the Box, the walls containing the rest of human life as she knows it. Enter S.H.E.P.H.E.R.D., the android here to figure out the truth of what happened to humanity, and save the remains from the Box's plans. They deem themself as the real hero of the story. And they know the majority of the human population didn't die out because of one simple plague. Secrets are revealed, lies are brought to light, and the citizens want justice. With a corrupt government, a hostile and deadly police force, mind-controlled firefighters and a dark, anarchist, yet secret organization holding the keys to the entire human race as they know it, nothing is safe. And nothing is solid. So what happens when that unimportant mail carrier receives a message that will turn the tide of the civil uprising?
