The protagonist is Domenico, the young Abruzzese who at the beginning of the 1900s leaves his native town (Aielli in the heart of the Marsica) to go to work, like many other Italians, abroad and whom we met in the previous novel "Mathematical Intrigue in Buffalo". His great "passion", formulas and mathematical relationships, which had already aroused the wonder of the architect Wright, make the famous architect want him with him for the construction of two new buildings that he was commissioned to design. But Domenico is tied to his Erminia, the beautiful girl with whom he is always in love, and who has remained in the village waiting for him. Conflicts with himself: Wright's proposal is tempting; in addition to guaranteeing him years of work, he recognizes the man's ability and makes him feel proud of his image, of what he has managed to build even if with little education. What to do? The choice is difficult. The choice is to give a setting to one's life, to one's future. What will prevail? Love for her Erminia and her family or satisfy her personal pride, income, work? Determined, resolute, convinced, he chooses after having meditated and considered everything possible, sure that the choice made is for his own good.Translated by Francesco Canizzi
