Cologne, the dawn of the 15th century. Winds of change and reform shake a Europe still ruled by deceit and old beliefs. The diffusion of knowledge is in the hands of a few. Nevertheless, a group of wise, erudite men who meet in secret are united by a common ambition: spreading culture among the people. How? Through books. But first they will have to overcome the reluctance of the Church and the nobles. Only one man, a modest goldsmith called Lorenz, helped by his daughter, will be able to face up to the challenge. But the price he may have to pay for such audacity is the most dear: his life and that of all those who surround him.
An intense, epic novel in which ambition, cruelty and intolerance fight against knowledge, justice and truth, and in which readers will immerse themselves and be carried along by the magic that surrounds books.
