Publisher's summary
''It's kill or be killed in the space penitentiary that houses the galaxy's worst criminals, where convicts face off in gladiatorial combat while an underworld gambling empire reaps the profits of the illicit blood sport. But the newest contender in this savage arena, as demonic to behold as he is deadly to challenge, is fighting for more than just survival. His do-or-die mission, for the dark masters he serves, is to capture the ultimate weapon: an object capable of obliterating the Jedi and conquering the galaxy.''

''Sith Lords Darth Plagueis and Darth Sidious are determined to possess the prize. And one of the power-hungry duo has his own treacherous plans for it. But first, their fearsome apprentice must take on a bloodthirsty prison warden, a cannibal gang, cutthroat crime lord Jabba the Hutt, and an unspeakable alien horror. No one else could brave such a gauntlet of death and live. But no one else is the dreaded dark-side disciple known as Darth Maul.''
