Beneath is a finely written, atmospheric science fiction thriller by Jeremy Robinson.

A scientist discovers a strange thing in the Arctic. Soon he starts hearing non-existent voices, then he dies. Scientific investigation occurs, and it turns out that the thing he found was an asteroid came from Europa, the sixth moon of Jupiter, and it carried microbial life. Global Exploratory Corporation sends a biologist, Kathy Connelly, alongside with her crew, to find out more. They melt their way through a many miles thick layer of ice that covers Europa, and submerge into the ocean beneath. They find life there: red, plant-like organisms there. However, the organisms are hostile and they did not want the crew to leave Europa alive…
The concept reminds me of Jeff Carlson’s novella The Frozen Sky, a dark fiction about
Alexis Vonderach, a smart and reckless young scientist who finds a strange amphibiant species in Europa’s dark, chilling cold caverns.
