Much to her surprise she enjoys the harsh military life and is quickly selected for officer training. But something's wrong, worlds are falling silent. There's no cry for help and no warning, just a sudden eerie silence. When a flotilla of ships is despatched to investigate they exit hyperspace to find themselves facing a massive alien armada. Outnumbered and outgunned the flotilla fight a rearguard action, allowing one of their number to slip away and warn mankind. As worlds fall in battle, and mankind's fleets are decimated, Selena is selected to lead a team of the Penal Regiment's most battle-hardened veterans, in a last ditch attempt to destroy the aliens' home world. If she fails mankind is doomed. Little does Selena know that one of her crew is a psychopathic killer and another is the husband of his victim. Can she hold her team together, get them to their target and succeed in the attack? Selena knows that if she fails then there will be nothing at all left to go home to.
