Publisher's Synopsis
Mars -- We thought it was for the taking. We thought we were the preeminent power in the universe. We were wrong.
Mankind's first colony on the Martian surface has fallen silent. The resupply vessel Murcielago, and its crew, are directed to assist with repairs. But within minutes of arriving, the ground team is attacked and the orbiting ship is infiltrated by two different alien species.
But we aren't the targets of these horrifying creatures - we're just underfoot.
