Tom is ten years old and different from oth-er children. He doesn’t like changes, red things, and anything noisy soon becomes too much for him. His specialty is space. He loves to run around in his astronaut suit and likes to wear a helmet in difficult situ-ations. When his mother unexpectedly has to go to China, Tom has to move in for six weeks with his siblings Nina (15) and Elmar (13) with their grandparents in rural Lunau. For Tom, this is a tragedy. But to make sure he makes it anyway, his mother gives him a logbook and suggests that he see staying with his grandparents.
