The challenge was enormous, but it seemed within the limits of the norm: the psychiatrist Marco Polo had to take twelve young people with various psychological problems and make brilliant disciples of them. Reality, however, turned humanity upside down and turned the world upside down. A terrible pandemic, caused by a highly contagious virus with a great capacity to mutate, caused deaths on all continents, and forever changed the way we socialize and communicate. Now, Marco Polo and his disciples face the new challenge with lessons on resilience, control, power, leadership and the search for well-being for all humanity. An exciting novel with profound lessons on individual growth and the common good, from one of today's most widely read psychiatrists.
