Beyond the Gate by Dana Davis
Space debris. I clean it up. I'm a simple woman who loves her job. I just want to do my work, make enough credits to buy a new shuttle, and have a little fun on the side. I never meant to put everyone in danger. I never intended to fall in love. And I never, ever set out to be a hero.
Centuries after the Great Exodus, humans spread out across the galaxy. And where humans go, garbage happens. Once a lonely orphan, Mouse now works in her chosen career as a space garbage retriever with Network. When she lands a job on a distant moon, Network assigns a man she's been attracted to since her training days as her partner.
Mouse and Samson work well together, but she begins to question strange events concerning the new job. Her rebellious actions get them stranded in an isolated area, where they uncover evidence that could implicate Network in crimes against humanity. Will Mouse and Samson find a way home and uncover the truth? Or will they remain in isolation for the rest of their lives?
