In the year 2031, a robot probe detects traces of biological activity on Enceladus, one of Saturn’s moons. This sensational discovery shows that there is indeed evidence of extraterrestrial life. Fifteen years later, a hurriedly built spacecraft sets out on the long journey to the ringed planet and its moon.

In 2005, the robotic probe “Huygens” lands on Saturn’s moon Titan. 40 years later, a radio telescope receives signals from the far away moon that can only come from the long forgotten lander.

Jupiter’s moon Io has an extremely hostile environment. There are hot lava streams, seas of boiling sulfur, and frequent volcanic eruptions straight from Dante’s Inferno, in addition to constant radiation bombardment and a surface temperature hovering at minus 180 degrees Celsius.

Russian billionaire Nikolai Shostakovitch makes an offer to the former crew of the spaceship ILSE. He will finance a return voyage to the icy moon Enceladus. The offer is too good to refuse—the expedition would give them the unique opportunity to recover the body of their doctor, Dimitri Marchenko.

After a long journey to Saturn’s moon Enceladus, spaceship ILSE is on its way back to Earth, carrying crucial cargo. The crew is exhausted and wants nothing more than a quick return home. Suddenly, a chain of malfunctions puts the expedition in peril.

All four bestselling books of the Ice Moon series are now offered as a set.
