"The most unloved foster daughter of the Griffin Duchy carries the realm's strongest healing magic. Sera once saved Lord Cedric and was adopted into his castle — only to be scorned by his three sons and outshone by a scheming maid, Lila. Hearing Valen say, ""Sera? She was never my choice,"" she stops caring. So she makes her own choice: to marry Caesar Enzo, the feared ""cold-blooded tyrant"" of the Obsidian Duchy. No one believes in this alliance. But the fire that has burned his body for twenty years finds its only water in her tears. ""I did not come for an alliance. Your existence is the only water I have ever found."" While her brothers kneel in regret, she walks into the abyss and becomes its first Luna — the queen who never feared its fire. Their child will never be locked in a dungeon again."
