Flipping Out!

Perfect for fans of Goth Girl, this addictive supernatural series is ideal for girls of 9+ to sink their fangs into...

The twins are adjusting to high school, but everything is still topsy turvy. Ivy's flipping out about being the most popular girl in school. All she wants is some time to herself! But her band of superfans are clinging to her tighter than bats to a cave. 

Meanwhile, Olivia is on a matchmaking mission. But will Queen Goth Amelia and Skater Boy Finn be able to put aside their differences and realise they are head over heels for each other?

These kinds of situations only happen in My Sister the Vampire. A vampire book for girls who want to read about young love and innocent paranormal romance. Ideal for fans of Jacqueline Wilson, Meg Cabot, and Zoe (Zoella) Sugg.

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.
