Sweeping through the Small Magellanic Cloud, leaving a trail of ravished worlds and destroyed civilization, is the Udef -- the Unidentified Death Force.
The best scientific minds of two galaxies can make nothing of it.
The Udef is invisible.
No scientific instrument can detect its presence.
The only marks of its passing are the screams of its victims and the piles of dead left in its wake.
Momentarily safe on the world of Montura, Jan Darzek's strategy against the Udeffalters.
He and his as.
