The twins are travelling to Transylvania!

Olivia's really nervous because she's meeting her vampire family for the first time. (There's a lot at stake.) Plus it doesn't help that she'll be there for Valentine's Day and her new boyfriend Jackson, the hot movie star, doesn't seem bothered that he won't be with her.

But it turns out it's Ivy who feels out of place, despite being surrounded by vampires! And Olivia's been noticed by Prince Alex, a smooth-talking handsome vampire with an eye for non-vamps.

Could it be love at first bite?

And what about Jackson?!

Sink your teeth into Olivia and Ivy's sixth fright-time adventure.
