Aliens: Stronghold — John Arcudi

Dr. Caspar Nordling is developing a micro-organism that is deadly to Aliens, but not to people. He's had a lot of luck engineering selective viruses to kill rats and weevils, but this is something altogether different. Highly speculative. Highly volatile. Just like the doctor himself. In a remote sector of the galaxy, on an isolated Grant-Corp space station, the thin line between science and horror is narrowing, and Philip and Joy Strunk, two company employees, are finding themselves on the short end of the cut.
