The infant is then left on the temple steps of Alzhor.

He kills her twenty times before she finally breaks the cycle. A peace treaty follows. Alira is sent to Devicit to marry Kalel.
In Devicit, Alira struggles with noble life. Kalel keeps her away from the palace gardens. He fears she will discover the truth.
The kingdom’s fertile ground and protective veil are sustained by the bones of thousands of slaughtered demigods. A goddess, Minerva, reveals this horror to Alira through visions.
Betrayed by Kalel’s second-in-command Tessa, Alira is thrown into the dungeon. She breaks free with Minerva’s help. While escaping, she overhears Kalel admit to the time-loop curse. Enraged, Alira runs to the gardens. She unearths a demigod skull.
She drinks the golden nectar of a peony and absorbs trapped souls’ power. The magical veil shatters.
The demigod army invades. Jupiter strikes with lightning. Alira and Kalel confront each other on a stone bridge. She summons Apollo’s golden arrow. He wields a devilstone sword. They mortally wound each other. Their gold and black blood mix on the snow.
They wake in Mortem, a peaceful underworld. Pluto and Venus explain that the gods orchestrated the loops to create one timeline with peace.
Kalel reunites with his mother in a quiet village. She urges forgiveness. The couple spends a week healing in a swamp cottage. They reconcile and share a night of passion.
Venus guides them to a wisteria pond.
They cut their palms. Their blood mingles.
They return to the living world. On the battlefield, both corrupt kings are dead. To stop the slaughter, Alira and Kalel offer themselves as a sacrifice of pure love.
They become marble statues with golden veins. Their blood restores a permanent veil and infuses peace into both armies.
