The voyage home by Pat Barker

After ten blood-filled years, the war is over. Troy lies in smoking ruins as the victorious Greeks fill their ships with the spoils of battle. Alongside the treasures looted are the many Trojan women captured by the Greeks - among them the legendary prophetess Cassandra, and her watchful maid, Ritsa. Enslaved as concubine - war-wife - to King Agamemnon, Cassandra is plagued by visions of his death - and her own - while Ritsa is forced to bear witness to both Cassandra's frenzies and the horrors to come. Meanwhile, awaiting the fleet's return is Queen Clytemnestra, vengeful wife of Agamemnon. Heart-shattered by her husband's choice to sacrifice their eldest daughter to the gods in exchange for a fair wind to Troy, she has spent this long decade plotting retribution, in a palace haunted by child-ghosts.
