Wrath Goddess Sing by Maya Deane

'The gods wanted blood. She fought for love. Achilles has fled her home and her vicious Myrmidon clan to live as a woman with the kallai, the transgender priestesses of Great Mother Aphrodite. When Odysseus comes to recruit the 'prince' Achilles for a war against the Hittites, she prepares to die rather than fight as a man. However, her divine mother, Athena, intervenes, transforming her body into the woman's body she always longed for, and promises her everything: glory, power, fame, victory in war, and, most importantly, a child born of her own body. Reunited with her beloved cousin, Patroklos, and his brilliant wife, the sorceress Meryapi, Achilles sets out to war with a vengeance. But the gods-a dysfunctional family of abusive immortals that have glutted on human sacrifices for centuries-have woven ancient schemes more blood-soaked and nightmarish than Achilles can imagine. At the center of it all is the cruel, immortal Helen, who sees Achilles as a worthy enemy after millennia of ennui and emptiness. In love with her newfound nemesis, Helen sets out to destroy everything and everyone Achilles cherishes, seeking a battle to the death.
