500 years ago, the invention of the printing press ignites the first information revolution. Brave souls risk torture and fire, working in secret to teach literacy. The church-state hunts them radicals and heretics, condemning their teachings and pacifism as a threat to wealth and the recruitment of armies. With their underground printing press, one small cell of idealists struggles to liberate others. They believe in equality of all people, all sexes, all races, and call themselves brethren. Capture means an agonizing death. This is their story, and of those who come to love them, and of those who relentlessly hunt them.
