Library War

In a slightly different timeline than ours, the explosion of information and misinformation came to be considered a direct threat to society. In a daring decision, it was decided to create a new government agency dedicated solely to information management. Some thirty years later, in 2019, the government still monitors and controls information, suppressing anything they find undesirable, but standing against their abuses of power are the libraries, with their special agents called ‘the book soldiers.’
