Set in Reformation Europe, Q begins with Luther's nailing of his 95 theses on the door of the cathedral church in Wittenberg and traces the adventures and conflicts of two central characters, an Anabaptist, a member of the most radical of the Protestant sects, the anarchists of the Reformation, and a Catholic spy and informer, as they travel across Germany, Italy and the Netherlands. The four young writers who shelter behind the pseudonym Luther Blissett have created a world of intrigue, violence and intense political and religious passion. Far from the traditional historical novel, Q is the stuff of which cults are made.
