Astrolabius is becoming a detective!
In the seventh book of the series 'Astrolabius Lives on the Moon', there are some mysteries to solve. First, the technical devices of the Lunar School go crazy, then the chaos spreads to the entire Lunar Station and suddenly all kinds of boxes and objects mysteriously disappear. Moreover, apparently no adult realises what is going on here. This is, of course, a classic case for the Lunar Team! Due to unexpected headwinds, Astro and Nolan are on their own. And in the vastness of space, an alien transport ship is holding position on the far side of the moon.
