Venice, 1244. A witch named Bettina watches her husband burn at the stake. Driven by grief and fury, she summons Poseidon—not a god, but an ancient sea law—and receives seven laws burned into her skin. Each law is a weapon. Each death she deals is a mirror of her enemy's deepest love. The banker drowns in gold. The judge is eaten by his own memory. The inquisitor beats himself to death with his prayer book. But the seventh law whispers: Do not avenge the living. Bettina has already killed four men when she learns that her husband may still be alive. Now she must choose: remember everything and carry the pain, or forget everything and lose herself. *With two possible endings, authentic 13th-century rituals, and a love story that spans forty-four years, Salt and Ashes of Poseidon is a haunting tale of magic, morality, and the cost of becoming a monster to destroy monsters.* *Narrated in immersive literary style. Perfect for fans of The Bear and the Nightingale , Circe , and The Witch's Heart .
