211BCE. The Roman invasion from the western seas is imminent, and from the south the Spartans are burning and pillaging their way north.

Battle-hardened Philopoemen believes the Achean League is facing annihilation if it does not arm. But without a formal army or cavalry, they don't stand a chance. Convincing his friend and healer Alexanor that the threat is real, together they begin to build a massive cavalry guard from the ground up — one that will fight on all fronts.

It is the last roll of the dice for the Achean League. But Alexanor knows Philopoemen is one of the greatest warriors Greece has ever known — the New Achilles. The Last Greek.
