Beneath (Origins, #3)
by Jeremy Robinson (2010)
When evidence of microscopic life on Europa–Jupiter’s sixth moon–is discovered, a crew of astronauts and scientists embark on a mission to discover its source. Led by oceanographer and biologist, Kathy Connelly, the crew is charged with the task of melting through miles of ice to the hidden ocean beneath, where the search for alien microorganisms begins. But a startling discovery awaits them on the surface of Europa–life.
After a string of mediocre books, it’s good to be back with an author who knows what he is doing. This story combines science fiction, action, horror and suspense. It’s up the the standard of his other books and the science is plausible (assuming life within our solar system is acceptable).
