The Vacuum of Space, Paperback

It's a dirty galaxy and someone has to clean it.
Avoiding the wealthy inhabitants on the upper levels of Station Kelly Kornienko is bot-programmer Triana's number one rule. Well, number two, right after "eat all the chocolate."

But when one of her cleaning bots finds a dead body, all the rules go out the airlock. A highly connected security agent interrupts her routine with stories of missing bodies, and Triana can't ignore him; it's cooperate or find a new job. A girl has to pay the rent, even on a crappy studio compartment.

Working with a shiny detective beats a shuttle dirt-side, so Triana lends her programming skills to Agent O'Neill's investigation. Together, they find more victims and evidence of a major cover-up.

It will take all Triana's technical talents, most of O'Neill's connections, and some really excellent croissants to stop the murders, save her job, and ultimately, her life.
