After a fateful carnival‑night encounter with ancient‑blood vampire count Sebastian, art restorer Evelyn bears their half‑vampire son Ethan, the millennium‑rare Day‑walker. Framed for death by power‑hungry uncle Victor, she hides for five years before reuniting with Sebastian at an art exhibition. Gifted with sunlight‑resistant flesh and healing blood, little Ethan becomes the target of pure‑blood conservatives and the greedy Victor. The family is pulled into brutal vampire‑clan intrigues, ancient altar prophecies and the sealed primal shadow menace. Together with allies from multiple factions, they overcome traps, rescue captives, resolve age‑old curses, reconcile light and shadow power, and win a new future where vampires may safely stand under the sun.
