Crastus has fought to retake the Seven Sisters fortress complex for one Emperor of Rome only for that Emperor to die at the hands of a rebel, pitching Crastus into political turmoil. Having been forced into choosing one of the two rivals for the throne Crastus had then had to defend the Seven Sisters from the legions of the other rival.

Sentenced to death by impaling for daring to do so, only the legions can save him. Forced to take the purple or suffer an excruciatingly painful death, the Emperor Crastus finds himself once more outside the walls of the Seven Sisters, with the gates closed and barred against him. Once more the legions must face their own in bloody siege. Only this time for Crastus, it’s personal.

The exciting conclusion to the Seven Sisters trilogy which began with ‘Seven Sisters’ continued with ‘Two Brothers’ and comes to a bloody climax in ‘Imperator’.
