The 'Bunny' twin is a vegetarian, which distinguishes them sufficiently when they socialize. Other than that, the vampires are pretty much your average middle schoolers, just a variation of humanity, with Goth tendencies and rapid healing abilities resulting in longer lives. They have evolved past murderous behavior (even filed their fangs!) They now satisfy their remaining blood lust with rare meat and red drinks. One is a Goth/Vampire the other is a Pink/Bunny cheerleader ('Bunny' being what the vampires in these stories call non-vampires.) Despite their extreme differences in self-expression, they feel an immediate love and appreciation for one another, even before they realize they are twin sisters. Twin girls separated at the age of one year old find one another at school.

Sienna Mercer has introduced some extremely tame vampires into the evergrowing lore. As an adult, I have enjoyed Ann Rice's vampire stories, Buffy the Vampire Slayer and most recently, Twilight, all of which are too adult and scary for my daughter. I am a big fan of vampire stories going back to Dark Shadows in my youth. She found the series in her elementary school library. I am very happy to have found stories to share that are smart enough for me and fun enough for her to read. My 11 year old daughter and I are reading this series together. She is happily writing away and we wait for her upcoming books! She lives in Toronto, kept company by Calypso and Angel – her two gorgeous cats. When she's not daydreaming about vampires and cheerleading, Sienna enjoys travelling and exploring new cities, and keeps a detailed scrapbook of everywhere she’s visited. who was a vampire? She loved the characters - and their kooky friends and family - so much that she just had to keep writing about them. Sienna got the idea for My Sister the Vampire from a daydream she had - what if she had a super-cool twin sister. She doesn't use red notebooks anymore, either, although she keeps them in a chest by her desk in the attic.

She used to write in red leather notebooks while sat on her bed, but now does most of her writing in her attic, which is quite dark, and has some spooky cobwebs in the corners - the perfect location for thinking about vampires. Sienna began writing stories when she was a teenager, on a very wet day in Toronto when her cheerleading practice was cancelled - and she has not stopped writing since. 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 books about a girl who reminded her of herself, and gave her the most fun, fabulous twin she could think of! She was an only child, and always wanted a brother or sister – especially a twin. Sienna Mercer grew up in Toronto, Canada.
