Have you collected all of 'My Sister the Vampire'?

Look out for Sienna Mercer's other great series, 'My Brother the Werewolf'.

Sienna Mercer grew up in Toronto, Canada. She was an only child, and always wanted a brother or sister – especially a twin. A twin would have been awesome! Sadly, she never got that sister so, when she was grown up, she did the next best thing - she wrote stories for girls about a girl who reminded her of herself, and gave her the most fun, fabulous twin she could imagine . . . a vampire twin.
