Rebel Sword by Peter Bostrom

Rating: WARTY!

Private Lucas Walker’s dead-end job on a tiny Pluto moon" Why? Are there no robots or AIs that could do this? And WTF is that job exactly? "...is shaken up when a spatial-temporal vortex opens and a deadly army appears." Thank god for that. An army that wasn't deadly would be laughable, wouldn't it? And what's with the sword? Naturally it's "First in a series." Barf.
