Few men have had in their hands the privilege of being able to change the fate of history, and those have done so through the war, spreading his time of death, destruction and pain. However, John Paul II, was a Saint who changed history with the strength of love emanating from a deep and sincere faith in God, a faith that led him to devote himself to others until his dying breath. The story begins in the days leading up to his death and going hand in hand with an illustrious group of people (like: Pope Benedict XVI, Cardinals Dziwisz, Oder, Ruini and others, his childhood friends and those who accompanied him throughout his ministerial exercise) we can follow the spiritual itinerary that made John Paul II became a Priest, Bishop, Archbishop, Pope and finally a Saint, through the major historical events of our time: the period between the World Wars, World War II, the Cold War, the Fall of the Berlin Wall, among others. Undoubtedly, John Paul II, is a holy for believers and for those who do not profess the Catholic religion he is the man who changed contemporary history and, for both, a model to follow today. In short, this book introduces us the life of John Paul II, showing us their personality, their feelings and emotions through the look of those who surrounded him, in such a way that they show us how the saintliness in his soul was being forged, the saintliness of the man called Karol Wojtyla.
