[1083] Aljis: Ruination, part 1

This is the third short story in this series, after the original Aljis and Aljis: Starstorm. I want to get opinions from people who haven't read the other stories...I don't think anything will be too weird if you are just jumping in here. For anyone who has read the first two, I'm interested in hearing your thoughts on this one as well.

Plot so far: Katherine Corrina, a half-robot soldier attached to Earth Army 2, has risen through the ranks on the desert planet Aljis, battling the monstrous worms and moths who call the place home. She eventually becomes commander of Pinnacle Base, where she has to uncover a clandestine plot led by an alien infiltrator. Afterward, she is promoted to colonel and given command of a capital ship built by the Centauri - onetime enemies of Earth now allied with humanity against invaders from Sirius. At the conclusion of the second story the Sirian Star Empire unleashes Operation Starstorm, an all-out attack on Aljis with the aim of clearing it of humans and Centauris and claiming its natural resources for themselves.

Thanks in advance for any critiques or Google comments.
