"Centesimus Annus" is a papal encyclical where the Pope explores and reaffirms the Catholic Church's teachings on social and economic issues. It was written on the hundredth anniversary of "Rerum Novarum," an earlier encyclical addressing issues of labor and the economy. The document discusses the dangers of both socialism and capitalism, and emphasizes the importance of a moral and ethical approach to economics, one that respects human dignity and prioritizes the common good above personal gain.

This book is a collection of the encyclicals issued by Pope John XXIII during his tenure as the head of the Catholic Church. The encyclicals, or papal letters, address a variety of topics including social justice, peace, human rights, and the role of the Church in the modern world. They provide insight into the Pope's theological and philosophical perspectives, as well as his vision for the Church and its mission in society.

The novel unfolds as a satirical adventure, delving into the complexities of faith, deception, and the human quest for meaning. Set against the backdrop of early 20th-century Europe, it follows the journey of Lafcadio, a young man whose paths cross with an eclectic mix of characters, including anarchists, aristocrats, and religious figures, each embroiled in their own pursuits of ideology, power, and salvation. Central to the plot is a meticulously planned hoax involving the Pope, which spirals into a series of events that challenge the characters' beliefs and intentions. Through its intricate narrative and sharp critique of societal norms, the book explores themes of morality, authenticity, and the absurdity of human endeavors.
