FIRST FLEET #1: BONES (SHORT STORY)
In a war many light years away, among the ruins of an ancient alien civilization, our fallen soldiers return from the front lines in pieces.
Medical pods regenerate the remains of these soldiers so their mind and consciousness can be downloaded into their freshly regrown body.
But something at the front lines... something inside the ruins... has been killing our soldiers faster than we could grow them.
When a pod arrives with more than just the pieces of a fallen soldier, what begins to regenerate inside is something unimaginably powerful.
If it awakens, we will have lost a war we didn’t even know we started.
