Animus by T. W. Iain

In a violent world, can the meek ever survive?
Ostar knows he’s nothing special. But he’s useful to the crew — not with the violence, but as a look-out. He’s never hurt anyone in his life. He simply wants to keep his head down and live without conflict.
But the crew are dying. Someone is killing them, one by one. And it is only a matter of time before they come for Ostar.
Aminusis a short story in the world of Dominions, but can be read as a stand-alone.
