Um Mundo Sem Fim, Volume I by Ken Follett

Set in the medieval town of Kingsbridge, the story unfolds two centuries after the events of its predecessor, weaving a rich tapestry of intrigue, ambition, and survival. The lives of four children are forever altered after witnessing a traumatic event in the forest, setting the stage for a saga that spans decades. As they grow, their paths intertwine with the town's fortunes, marked by the construction of a new cathedral, the ravages of the Black Death, and the relentless pursuit of power. Amidst the backdrop of societal upheaval, personal vendettas, and forbidden love, the characters navigate a world where the struggle for justice and progress is as enduring as the stone structures they seek to build.
