Agent Six of Hearts is back in another high-octane adventure. And this time - it's personal! The evil Methryn Crexe, the mastermind behind the superhuman assassin project, has been rescued from the Deck's supposedly impenetrable prison. The Deck agents follow his trail to a disused apartment block where they are ambushed by a highly trained, mysterious army. At the height of the fierce shootout, Kyntak, Six's clone, is kidnapped. As Six scours the City for his brother, a strange girl appears as his protector; he becomes increasingly aware of a sinister power; the Deck is put into lockdown - and the clock ticks steadily against Kyntak's life... Once again, Six of Hearts is on the run: from his past, his fellow agents, even his own DNA...
