When a new breed of social media goes viral, schoolteacher Henry Hubert warns his students to steer clear of the website. Backspaced is unlike anything the world has ever known. The site allows users to rate their peers, anonymously, using review commentary and a star rating system. Rate whomever you like, or dislike, as often as you like, the choice is up to you. Meanwhile, in a bizarre twist of fate, two long-feuding families find themselves sharing a Saint Paul hospital waiting room. With no place to run, they are forced to put their differences aside. Back in their hometown, with two of his students in critical condition, Henry drives to the hospital to show his support. Suddenly, without warning, the city is placed under quarantine. The group in the waiting room soon learns the shocking truth: the quarantine spans the entire planet. "Bio-terrorists" have poisoned the atmosphere. An invisible, highly-toxic substance is now slowly falling to the earth. The Sixth Great Extinction has begun. The only good news is there is a vaccine to protect some of the population. The bad news is that supplies are woefully inadequate and the government is using technology to decide who will survive. A story as current as tomorrow's headlines: Backspaced will make you rethink everything you know about social media.
