The Peloponnesian War has begun. An army of merciless Spartan invaders have arrived at the gates of Plataea, bent on obliterating the city and its inhabitants. Plataea's oldest allies, the Athenians, are spread too thin in their own campaigns to send help. Cut off and alone, the Plataeans dig in behind their high walls for the coming siege, while the ruthless Spartans gather outside. On a rugged mountain road, a young Plataean warrior named Nikias rides to Athens on an urgent quest. He carries with him a bag of ill-gotten gold, hoping to raise an army of mercenaries to help defend his city from the coming Spartan assault. But in the sprawling stronghold of Athens, Nikias encounters perils that prove to be more dangerous than those he has faced on the battlefield. Noble Smith's Spartans at the Gates is a thrilling action-adventure novel set during the war between the great powers of ancient Greece.
