Santa's claim

Shy, plus-sized Sharon's life is upended when she's abducted from her world and presented to Santa Claus, a dominant and eternally young elf lord who rules a hidden winter realm. Overcome with a lust that feels like destiny, Santa initiates the 12 Days of Christmas, an ancient ritual of erotic trials designed to forge her into his Mrs. Claus and renew his waning magic. As Sharon sheds her inhibitions and embraces her desires under Santa's firm tutelage, she attracts the attention of Fenrir, his rugged and wild werewolf head of security. Fenrir offers a contrasting taste of freedom and raw passion, igniting a fierce rivalry for Sharon's heart. Unbeknownst to her, Fenrir is the secret heir of the rival Winter Court, sent to sabotage the ritual. As the trials escalate and the solstice deadline looms, Sharon is caught in a tug-of-war between two immortal lovers, while a conspiracy to plunge the world into eternal winter threatens to destroy them all. She must make an impossible choice, not only for her own heart but for the fate of Christmas itself.
