The Sleeping Keepers (5) Much has happened on Mars since the discovery of the blue towers and the sleeping aliens. But what began as a hopeful rescue of the Mars project is now threatening to become the doom of the whole world. Because the signs are multiplying: not only on Mars, but also on Earth, the aliens Carl discovered in the glass caves have left their traces. The aliens are still asleep. But what if they awaken? Are they friend or foe? The Martian children bravely face this question and make an incredible discovery.
