**In the fifth century BCE, as war raged between Athens and Sparta, two women found each other across the great divide of politics and bloodshed. Althea of Athens was a philosopher’s daughter, known for her sharp tongue and sharper mind. She spent her days beneath the marble columns of the Agora, debating ideas and writing poetry about the gods and the stars. Her city revered wisdom, but it frowned upon passion that burned outside the bounds of tradition.

Kalliane of Sparta was different—born of shield and spear, raised with the strength of a warrior and the silence of a soldier. She had known battle since girlhood, her hands calloused by sword hilts, her voice used more for war cries than whispers.**
