The Void — D.J. Goodman

At the ends of known space, on the edge of darkness, a space station floats in the emptiness. It is a place out of legend... and a symbol of pure evil. Two hundred years ago Captain Melissa Harvey brought genocide across the galaxy before all the known worlds banded together to kill her. Professor Vichna Lashke, along with a crew of marines for hire, has searched far and wide looking for the captain's fabled lost treasure. Now that they've found it, all they need to do is go into the station known as the Void and get it. That's when the nightmare will begin. That's when Vichna and her crew will need to fight for their survival. That's when they will discover there is far more in the Void than they ever thought possible
