Los diez escalones

Kingdom of Castile, 1283 AD. C. Alvar León de Lara, cardinal of the curia, returns at the request of his former mentor to the abbey that was his home, which he left twenty years ago with his soul broken by an impossible love. His teacher wishes to reveal something to him that will change the course of Christianity. However, the arrival of Alvar will unleash the tragedy: riddles behind hidden doors, inexplicable crimes, symbols that lead to clues and clues that lead to traps. A dizzying descent that will confront him with the woman who tore her heart apart, the intransigence of cowards, the struggle to stay among the living and, finally, the Ten Steps.
