The Legion / Simon Scarrow.

"When the actions of a rebel gladiator in Egypt threaten the stability of the Roman Empire, Acting Prefect Cato and Centurion Macro know he must be stopped. Ajax and his crew have been attacking naval bases, merchant vessels and villages along the Egyptian coast, stirring up anti-Roman sentiment by posing as Romans. With the southern frontier under raid by the Nubians, Egypt has become dangerously volatile. Tasked by Egypt{u2019}s governor with tracking and defeating the renegade before the situation worsens, Cato and Macro are soon hot on Ajax{u2019}s trial. Joining with Legion III, they are determined to destroy the enemy. But will the combined strength of a psychotically fatalist gladiator and his Nubian supporters, hell-bent on destruction, be the force finally to defeat the Roman warriors?"-- Publisher description.
