Publisher's Summary[]
Wilks, Billie, and Bueller were the last survivors of a devastating assault on the aliens' home planet. But their return to the solar system made them refugees once more, fleeing Earth and its alien infestation in a desperate attempt to stay alive. Now in an otherwise unmanned military transport, they hurtle through space. Destination: Unknown.
Little do they know the cargo they carry with them is a legacy of death that they will ultimately have to face. Nor do they know they head toward a remote colony and military outpost. This pocket of humanity at the very edges of space is at the mercy of a general named Spears with an agenda all his own. Now Billie, Wilks, and Bueller face a new nightmare, and it is nothing they could ever have imagined: a gift of madness from an alien world, an unbalanced mind and the experiences of a mysterious pilot named Lieutenant Ellen Ripley.
