John Carpenter's Tales of Science Fiction: Twitch (John Carpenter's Tales of Science Fiction: Twitch #5)

Unless an ex-cop who hasn't fired a gun in 15 years can muster up the strength to step into the most dangerous place on Earth, facing the most hideous creatures imaginable, lining up a desperate long shot, praying her hand doesn't twitch.
