From the bestselling author of CENTURION, THE GLADIATOR and PRAETORIAN, a new military adventure for battle-hardened centurions Macro and Cato, fighting for the Empire in Britannia. For nearly ten years, the Roman Empire has fought ceaselessly to strengthen its hold over Britannia. But opposition from native tribes led by the ruthless warrior Caratacus threatens to destroy everything. Prefect Cato and Centurion Macro are summoned by Governor Ostorius to Londinium. Tasked with leading a newly formed cavalry cohort into the heartland of Wales, they must destroy the growing resistance. But with Caratacus hatching increasingly ambitious plans and disorder threatening from within Macro and Cato's own ranks, this final test will push the soldiers to their limits. And if they do not emerge as victors, the Emperor Claudius's rule may be at stake, and the very foundations of the Roman Empire could be shattered irrevocably.
