Luka and Terezka are once again going on an exciting journey with the Magic Atlas. They find themselves in Greenwich, a suburb of London. This is where the zero meridian passes, dividing the world into the Eastern and Western hemispheres. An ancient observatory, an acquaintance with Professor Chambers, many interesting things about the life of sailors and the development of geographical science - all this awaits young readers in the second book of the trilogy by Nadiya Gerbish.
