The man on the meteor

"The Man on the Meteor" by Ray Cummings is a science fiction adventure that throws a mysterious man named Nemo onto an alien meteor circling Saturn. Waking up with no memory, Nemo must figure out who he is while navigating this strange new world, instantly dealing with the challenge of figuring out the low gravity physics. Almost as soon as he removes his suit, he meets Nona who appears to “swim” with ease through the air. Together, Nemo and Nona find a safe cave to live in, where they start to build a bond, but now face the unique challenges of surviving and understanding the bizarre world they find themselves in, filled with equally strange Marinoid creatures.
