Titan

A team of four astronauts is sent to Saturn’s moon Titan to explore the methane seas and search for signs of life that may have originated on Earth and been transported to Titan when meteors hit the Earth during its formative period.
When they arrive, they find evidence of a much older culture with technology they cannot even comprehend. The machinery they find under Titan’s ice is still active. It’s been waiting for them.

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

Narrated by Siri

Really enjoyed the story but holy crap it was a hard listen due to the mechanical narrator. She went back and forth on pronunciations of names and all kinds of things it was extremely distracting.
