My Sister the Vampire Books in Order

How to Read the My Sister the Vampire Series

Welcome to Franklin Grove, a seemingly ordinary town with a huge, dark secret: it is home to a thriving community of vampires! At the center of this world are Olivia Abbott and Ivy Vega. Olivia is a bubbly, pink-loving cheerleader who just moved to town, while Ivy is a pale, goth girl who happens to be a vampire. When they cross paths, they discover they are actually identical twin sisters separated at birth. What follows is an 18-book series filled with twin-swapping shenanigans, high school drama, and vampire secrets.

Because the series is highly episodic but features a continuous character-arc development (especially regarding the twins' relationship, their family secrets, and their romantic interests), the best way to read the series is in chronological publication order. Starting with the first book ensures you understand how Olivia fits into the supernatural society of Franklin Grove and how the twins navigate their newly discovered bond.

Understanding the UK vs. US Title Confusion

If you are collecting physical copies of these books, you might run into some confusing title variations. Because the series was published in the United Kingdom by Egmont/HarperCollins and in the United States primarily through Scholastic, several books were renamed for different markets. Here is a handy comparison to make sure you do not buy the same book twice under different names:

• Book 8: Known as Star Style in the UK, but retitled The Bat Pack in the US.
• Book 9: Known as Twin Spins! in the UK, but retitled Twin-Tastrophe in the US.
• Book 10: Known as Bite Night in the UK, but retitled Date with Destiny in the US.
• Book 11: Known as Flying Solo in the US, but sometimes released under alternative titles like Vampire School Dropout? in the UK.
• Book 12: Known as Stake Out! in the US, but sometimes titled Read It and Creep in the UK.
• Book 13 / 18 Confusion: In the UK, Book 13 is titled Double Disaster!, while Book 18 is titled Fangs for the Memories. However, in the US, Scholastic published Book 13 under the title Fangs for the Memories. If you are reading the US editions, Book 13 is your Fangs for the Memories, whereas UK collectors use that title for the final book.

The Spin-Off: My Brother the Werewolf

If you finish the main series and want more paranormal middle-grade fun in the same universe, Sienna Mercer also wrote a spin-off series called My Brother the Werewolf. This series shifts the spotlight to twin brothers Daniel and Justin Packer. Just like Olivia and Ivy, they are identical twins with a massive supernatural twist: one of them is destined to become a werewolf on his thirteenth birthday. The spin-off consists of four books, which should be read in this order:

1. Cry Wolf! (2013)
2. Puppy Love! (2013)
3. Howl-oween! (2013)
4. Tail Spin (2014)

What to Know Before You Start

The series is written under the pen name Sienna Mercer, which was utilized by a creative team working within a fiction mill to produce these collaborative novels. This collaborative writing style explains why the books are highly consistent in their light, fast-paced, and engaging tone. The series is squarely aimed at middle-grade readers (typically grades 4 to 8, or ages 9 to 12) looking for a 'vampire-lite' experience. There is no horror, gore, or terrifying lore here—instead, you will find a focus on friendship, fashion, cheerleading, and the comedic challenges of living in a town with a secret vampire population (featuring funny details like the local BloodMart supermarket).

While the overall plot develops across the books, each installment is relatively self-contained, meaning you can occasionally read them out of order without getting completely lost. However, to fully appreciate the growth of Olivia and Ivy's sisterly bond, starting at the beginning with Switched is highly recommended.
