Rhea

Five years have passed since the disappearance of the crew of the Titan Explorer. In that time many probe missions have been sent to Saturn to gather details of its moons. The spaceflight program in the U.S. has all but been replaced by a private company with strong links to China. Most new spaceflights beyond the Earth now launch from the Moon. One of those flights contains a team of miners tasked with drilling into Saturn’s moon Rhea. A second flight is being prepared for a science mission below the surface of Rhea. What the Rhea missions find is not what they expected.

Rhea is the second book in the series: Titan, Rhea, Tharsis.
