Rut has to run away. From whom? Why? She knows that she doesn't have a choice but she doesn't know the reason. Even the people who want to help her like Professor Argimon and Marc the anchovy are surrounded by secrets... What do the people after Rut want from her? Where will she go? Why? 'Caminos de noche' ('Journeys by Night') is the first instalment of the 'La luz de Artús' ('The Arthur's Light') trilogy. It doesn't contain the answers to all these questions, but it does offer some, although we might not always like them. The trilogy doesn't take place in our world, or at least not in our world as we know it. History has gone in different directions. There are similarities and you can see familiar elements in the geography of some countries, but the borders are very different. It is as if the Spanish civil war had taken place twenty years earlier and was still ongoing at the outbreak of World War II.
