FreeFall. The Backworlds, #7

The first shot of a new war echoes through the galaxy. Craze has high hopes for what the alliance with an old enemy, the Foreworlds, will do to defeat a worse enemy, the Quassers. The test of a highly-advanced weapon, created by the efforts of the alliance, pushes tensions over the brink and kills thousands. To make it worse, the Foreworld ambassador is keeping secrets. Conventional warfare against the Quassers isn't working, and if the alliance ends, Craze has become the most hated man in the galaxy for no reason.
With nothing left to lose, Craze sets in motion one last chance for survival.
