Rosangela: The Half-Blood Princess

Rosangela was kidnapped by a group of vampires and brought to their kingdom only to find out that she's actually the vampire king's granddaughter. Rosangela Sinclair was an orphan who lived with her adopted family in London. One night, Rosanne, short for Rosangela, was kidnapped by a group of vampires and brought to the vampire kingdom to meet their king, King Bellamy. The vampire kingdom claimed that Rosangela was Princess Mirabelle, his missing granddaughter whom he had been tracking down for years. Thus, it made Rosangela become a half-blood vampire Princess.
