Dr. Julian Croft, a brilliant but unassuming professor of Roman history, has spent his life studying the campaigns of Julius Caesar. His expertise is purely academic, a world of dusty books and theoretical battlefield analyses. During a historical reenactment, a freak accident with a piece of faulty siege equipment ends his life. He awakens with a gasp, not in a hospital, but on the hard, unforgiving ground of a Roman marching camp. He is no longer a professor; he is Titus, a young, barely-trained legionary in Caesar’s famed Tenth Legion, on the eve of the grueling Gallic Wars. Armed with a historian’s perfect foreknowledge of the battles to come but trapped in a body that has never known true combat, Titus must survive the brutal reality of the life he has only ever studied. His fight is not just against the fierce tribes of Gaul, but against the crushing weight of his own secret: the knowledge of who will live, who will die, and how the fate of the Roman Republic will be forged in the blood and mud of this very campaign.
