Description Set in the far future, Earth's appetite for natural resources has become a major motivator for deep space exploration. Immense, privately-owned and operated mining ships called "planetcrackers" orbit planets and use sophisticated equipment to carve out entire city-sized chunks of rock, reducing them to component elements and raw ore. When communications go dead onboard the USG Ishimura, a famous planetcracker, systems engineer Isaac Clarke is sent in to fix the problem. Once onboard the vessel, Isaac discovers that the crew has unearthed an ancient and malevolent alien presence far beneath the planet's surface and brought it onboard. Weaponless, alone and terrified, this lone engineer is burdened with much more than simple survival - he must seal the alien horror back into the dark rock.
