The critically acclaimed author of Alien: The Cold Forge takes readers to a rogue colony where terror lurks in the tunnels of an abandoned Weyland-Yutani complex.“Shy” Hunt and the tech team from McAllen Integrations thought it was an easy job—set up environmental systems for the brand new Hasanova Data Solutions colony, built on the abandoned ruins of a complex known as “Charybdis.”  There are just two problems: the colony belongs to the Iranian state, so diplomacy is strained at best, and the complex is located above a series of hidden caves. Charybdis has a darker history than any could imagine, and its depths harbor deadly secrets. Until their ship can be refueled, the McAllen team is trapped there. The deeper they dig, the more Shy is convinced there''s no one they can believe. When a bizarre ship lands on a nearby island, one of the workers is attacked by a taloned creature, and trust evaporates between the Iranians and Americans. The McAllen integrations crew are imprisoned, accused as spies, but manage to send out a distress signal... to the Colonial Marines.
