The Gods of War — Conn Iggulden

The year is 53 B.C. Fresh from victory in Gaul, Julius Caesar leads his battle-hardened legions across the Rubicon river. From here, there is no turning back from is destiny. Now the armies of Rome will face each other at last in a bloody civil war, led by the two greatest generals ever to walk the seven hills. Yet even as this monumental battle rages, another kingdom beckons Caesar--a world of ancient mysteries and languid sensuality and the seduction of an Egyptian queen named Cleopatra, who will bear his only son. From the spectacles of the arena to the whispered plots of conspirators, The Gods of War follows Julius Caesar through politics and passion, ruthless ambition and private grief--and an extraordinary friendship marked by fierce loyalty... and bitter betrayal.
