When an Oxford undergraduate encounters the enigmatic Aleriel, a disguised alien from Venus, he embarks on an extraordinary journey that takes him through war-torn Paris, bustling London, and serene Oxford, ultimately leading to a quest for truth about humanity and the cosmos. Aleriel's exploration of Earth and his subsequent adventures through the solar system highlight timeless themes of curiosity, friendship, and the search for understanding beyond our world.
