A brutal prequel to The Centurion of Caesar . Before the crossing of the Rubicon, before the Civil War, Flavius was just another legionary—one of tens of thousands marching through blood and mud in Caesar’s legendary Gallic Wars . Once more told through the eyes of Flavius, Under Gaulish Skies plunges you into the raw, unforgiving campaigns that forged the Roman Empire’s northern frontier. From the burning villages of rebellious Gauls to the storm-swept shores of Britannia, Flavius and the Thirteenth Legion fight not just for survival, but to impose Roman order on a world that still howls in chaos. Alongside his loyal companion Valerius, and under the command of Gaius Julius Caesar , Flavius faces savage tribes, betrayal, and the eternal clash between civilization and barbarism. For readers who crave war without mercy, heroes without weakness, and Rome without apology—this is your war.
