An immortal race freed by death and defiance of the gods. Hundreds of years of peace have reigned since the treaty between the Amazon nymphs and the gods of Mount Olympus. The edict forbids the Amazon nymphs to leave their isle of Azure Blue. But Azure Blue is threatened as the continent of Atala is fractured by war. As nymph queen Delia grieves the death of the king who once united them, her unruly daughter, Avva, wishes to mourn him in her own way. Avva plans a flyover with her unicorn beyond the Strait of Azure. Such hubris forces sacrifice. Nymphs fall to the Underworld. In the depths, they find Cora, the goddess Persephone. And Cora might be the only goddess willing to risk her family's wrath and help them. After all, Cora has fallen from Azure Blue before.
