After proving himself as a formidable cavalry commander, Marcus Antonius finally earns a position at his kinsman Julius Caesar's side. However, Caesar is an exacting general, demanding complete allegiance from his staff, even when his decisions put him at odds with the Senate. Marcus's loyalty to Caesar comes at a cost, and he soon finds himself embroiled in mob violence and military mutinies. As civil war brings Rome's Republic crashing down, many a relationship is torn asunder, including Marcus's marriage. Determined to rise triumphant in Rome's new era, Marcus faces his fears, his failures, and his enemies--not the least of whom is himself.

Amid the crisis of the Ides of March, Marcus must don the mantle of ruthlessness to carve his own legacy in Rome's history. Enemies have been made, wills have been read, and heirs proclaimed.

But in Rome's civil unrest, blood answers only to blood.
