Derrick Fitzgerald, the author of the new book titled "Retrorsum," has dedicated many years to extensive travels from the early 1980s to the present day. His journeys have taken him to every continent, except Antarctica. Alongside his passion for exploration, he indulges in various cultural activities, immersing himself in music and culinary delights from diverse corners of the world.
