Dark Matter

From publisher blurb: The travelers are hired for a delicate mission. A hacker has acquired some sensitive material and has brought it to a casino space station. He intends to sell it there to an interested buyer. The patron offers a significant sum to terminate the hacker and retrieve the documents before this happens. The only problem is that the patron does not know what the hacker looks like. Another problem is that the patron is lying about why she wants him dead. And of course.....a hit aboard a crowded casino and hotel in space... what could go wrong?
