The ancient city of Troy has withstood a decade under siege of the powerful Greek army, who continue to wage bloody war over a stolen woman–Helen. In the Greek camp, another woman watches and waits for the war’s outcome: Briseis. She was queen of one of Troy’s neighbouring kingdoms, until Achilles, Greece’s greatest warrior, sacked her city and murdered her husband and brothers. Briseis becomes Achilles’s concubine, a prize of battle, and must adjust quickly in order to survive a radically different life, as one of the many conquered women who serve the Greek army. When Agamemnon, the brutal political leader of the Greek forces, demands Briseis for himself, she finds herself caught between the two most powerful of the Greeks. Achilles refuses to fight in protest, and the Greeks begin to lose ground to their Trojan opponents. Keenly observant and cooly unflinching about the daily horrors of war, Briseis finds herself in an unprecedented position to observe the two men driving the Greek forces in what will become their final confrontation, deciding the fate, not only of Briseis’s people, but also of the ancient world at large. Briseis is just one among thousands of women living behind the scenes in this war–the slaves and prostitutes, the nurses, the women who lay out the dead–all of them erased by history.
