Nowadays, Keith Livingston meets his great-grandfather named Cosimo in an ordinary London alley. He briefly told Keith about ley lines, flows of telluric energy in the body of the earth, marked on the surface in one way or another. Ley lines allow you to move not only in space, but also in time, as well as move into other realities. Quite a long time ago, there lived a man who knew more about ley lines than others. He traveled through time and space, and in order not to get lost in his wanderings, he developed a complex cipher - a road map of symbols - and applied the routes of his movements to his own body in the form of tattoos. Over time, the Map on the Skin was divided into parts and hidden in different worlds and times. The task of people exploring ley lines is to find parts of the map. The point is not even in the map itself, but in the fact that among the various routes of the pioneer there is one leading to an extremely important object. The series “Bright Empires” by the famous writer Stephen R. Lawhead is a unique combination of descriptions of the pursuit of treasure, ancient history, alternative realities , advanced physics, philosophy and theology.
