Lord of Exiles - The Quintorius Chronicles, #1

EXILE - They took his land, his titles, and his command. And with a Dictator ruling the Namorian Republic, the Senate groveling over the scraps, and an unholy cult rising from the shadows, Aulus Septimus Quintorius must now flee before they take his life. TRAITOR - Proscribed to decorate the Forum with his skull, Quintorius knows he'll never see home again. Those that still follow him have little hope of legitimacy and accept the brand of traitors and dead men.
But they know nothing keeps Quintorius down for long. HERO - In world riddled with tyranny, rebel movements flourish aplenty, but leaders are rare. The oppressed cry out for freedom, the legions clamor for a general, and the Gods demand a redeemer. They're all about to get one.
