The novel is a metaphysical narrative about a doctor named Ricardo Reis who returns to Lisbon, Portugal after learning about the death of his friend. He finds himself in a society on the brink of dictatorship, and as he navigates through his daily life, he encounters his deceased friend's ghost and a hotel maid with whom he begins a love affair. The book explores themes of identity, love, and the nature of reality, set against the backdrop of political turmoil.

This novel offers a provocative and humanized retelling of the life of Jesus Christ, diverging from traditional biblical narratives. It presents a Jesus who is all too human, grappling with the complexities of life, love, and a sense of destiny. Through a blend of biblical lore and imaginative fiction, the story explores themes of divinity, free will, and morality, challenging readers to reconsider the foundations of faith and the nature of storytelling itself. The narrative delves into Jesus's relationships, his encounters with figures such as God and the Devil, and ultimately portrays a deeply philosophical and introspective version of a figure central to Western civilization.

"Mensagem" is a collection of 44 poems that pay homage to Portugal's heroic past, particularly its Age of Discovery. The work is divided into three parts: the first part focuses on the country's mythical origins, the second part celebrates the nation's maritime explorations and discoveries, and the third part reflects on the decline and future resurrection of Portugal. The author uses symbolic and allegorical language to convey his deep love for his homeland and his belief in its potential for greatness.
