¿Quién se comió mi planeta?

Something is destroying the books on Astronomy in the school library!!! Could it be a virus or is it a star thief? It's one of the most complex cases the Panda at the Bottom of the Class will have to face. The reader or spectator who ventures into these pages will also have to be on the alert to help our heroes solve this new puzzle. Theatre to read, theatre to perform, theatre to play, theatre to learn. Actors and stars, the universe on a stage.
