In A Nutshell
Heavy Space is about Mia V. and her outcast band of robots who accidentally kick off the fourth (and possibly last) Galactic War.
A Slightly Larger Nutshell
After a rough batch of years, working a bunch of deep space repair contracts, Mia Loses her husband, escapes an unpleasant death, and becomes hunted by just about everyone. Even her friends.
The only things keeping her alive are her robot crew and her ship, a flying pile of chaos called the Orca-12.
