The Vacuum of Space: Space Janitor Book 1

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 of 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.
The Vacuum of Space is the first book in a completed series.
