Cassandra 

Cassandra is the second in the Delphic Women trilogy. Doomed, magnificent Troy is burning… Cassandra, the golden-haired princess cursed with the gift of prophecy, and Diomenes, the Achaean with the healing hands, become puppets of the gods. Their passions are thwarted, their loves betrayed, their gifts rendered useless for the sake of a wager between two immortals. Will Cassandra and Diomenes find each other in the light of the burning city? And, if they do, can their love survive the machinations of malicious gods and men? The Delphic Women trilogy: Medea, Cassandra and Electra.
