Secrets and spies

Sink your teeth into Olivia and Ivy's 15th fright-time adventure There's always a lot of stuff to keep hidden in Franklin Grove (like, um, the fact that vampires exist), but suddenly everyone seems to have gone into secrecy overdrive! Ivy's sure that new girl Maya is up to something, and it involves Ivy's boyfriend, Brendan. Twin sister Olivia wants to help her get to the bottom of it, but first she has to work out what's up with their stepmom. She's behaving like a zombie--which is super weird for a vampire.
