The High Cathedral of St. Peter, commonly known as Cologne Cathedral, is a unique sacred building that has been a point of attraction for centuries, not only for pilgrims but also for travelers from all over the world. Our author Peter vom Falkenberg takes the reader on a fascinating journey back in time to the early phase of the cathedral's construction. With an eye for historical detail, he narrates the thrilling story of the carpenter Michel from Flensburg, his eventful journey to Cologne, his rapid rise in the construction of the cathedral, and his dramatic fall when he is accused of a brutal murder. At the same time, his stepbrother Tristan embarks on a quest for his past and encounters a mysterious Viking tribe oppressed by a tyrant. The reunion of the brothers in the Bergisches Land, the decisive battle in the far north, and a wedding in Cologne Cathedral.
