Astrolabius "Astro" Winter has only just settled into life on the lunar station when the next challenges are already waiting for him. At Moon School, unusual subjects such as rocket technology, cosmology, and hydrology are on the curriculum – and, of course, Erik Stone never misses a chance to make Astro's life difficult.

Then there's a girl's birthday coming up, and Astro urgently needs to find the perfect gift. What seems like a simple task at first quickly turns into a new adventure.
Luckily, Astro can count on his best friend Nolan and his faithful dog, Sternschnuppe. And when the Winter family sets out to trace the history of the first lunar station, Astro discovers a fascinating side of his new home: How did life on the Moon actually begin – and what stories are hidden in its past?

Between Moon School, friendship, and exciting discoveries, Astro realizes more and more: On the Moon, a new adventure is waiting around every corner.
