Bug Hunt — Stephan Michael Loy

Mars didn't work out. After all the excitement of the unmanned probes, the first manned mission to the red planet ended in failure. On top of that, redeployment back to Earth failed. Twice. Now the frazzled crew, wounded by creeping misanthropy, squalid living conditions, and the violent death of one of their own, must deal with an emergency no one could have conceived. They have learned that terror is not always a product of the dark, not always a thing that enters from without. Sometimes, you create your own worst monsters.
Bug Hunt is a creepfest, a story that will keep you jumping at shadows at the fringes of your vision, and feeling things touching you you'd rather not imagine. Happy Halloween!
