Unkind by Timothy Ellis

Lyla Cowan has given up fighting the changes in her life.
The Unbound Mercenary Company is expanding ahead of schedule, and she’s just rolling with it now.
They’ve made a name for themselves fighting pirates.
But there are always more pirates.

The human spine is on the way back to Ralnor space, if you take a dogleg.
And with the lower end opening up for new colonization at long last, the piracy problem there needs a solution.
What do you do with the unkind element making lives harder?
You get Lyla interested.
When Unkind is as Unkind does, you need the Unbound.
