A hidden mystery in Jupiter's second-largest moon holds a power beyond imagining.Beneath the icy surface of Callisto lies an underground sea. Decades ago, a research base was built to study the strange lifeforms inhabiting this silent world before tragedy struck, killing everyone. News of this incident is quickly hushed up, with all access to the Jovian moon restricted.

Kirill Sereda was orphaned when his mother never returned from that very outpost. Now an adult, he gathers together a team of misfits for a clandestine mission: head to Callisto and find out what really happened.

What they uncover is a profound enigma that could shed light on humanity's true origins, and its revelation could bring about an ultimate extinction.

Suitable for fans of Alien, Event Horizon, Interstellar, and The Expanse.
