A Rock and a Hard Place — Ryk Brown

Two worlds preparing their defenses . . .

A ship struggling to get back in the fight . . .

An enemy continuing its relentless attack . . .

A former enemy that could hold the answer . . .

With the fate of billions in his hands, Captain Scott is offered a way to save them all and end the bloodshed, but if it backfires, he could lose everything.

Sometimes, there is no good choice.
