AU: Instead is being sold to the cult, the twins are sold to a Duke with a secret. The moon is my sun, the night is my day, blood is my life and you are my prey. For as long as the twins can remember, they've always been with their Daddy. They've spent their whole lives spoiled and taken care of, since they were so fragile they might shatter at the slightest touch. Only Daddy had gentle enough hands to touch them. Or, in which Sebastian has manipulated the twins into having Glass Delusion and slight Peter Pan Syndrome. The title is Latin for "Sweet Little Dolls".
