One man. One planet. One destiny. Frederick Frater leads a hum-drum existence working in a Victorian bookshop. But one day an apparition walks into the shop - a beautiful young woman. Her father's extraordinary invention changes Frederick's life. The adventure that follows takes us back to Roman-occupied Britain and into the future, in which magic has become science. It is a future that Frederick can influence through his interventions - for he is one of the Chosen, a select and privileged group with the fate of the world in their hands.
