Howl-oween!

The third title in the warm, funny spin-off series from My Sister the Vampire

It's Halloween , but twins Daniel and Justin aren't about to be spooked by ghosts and pumpkins—after all, one of them is a werewolf! But there's still plenty to be scared about—like knowing when to hold your new girlfriend's hand, and having to swap identities to keep your biggest family secret safe. Trick-or-treating has never been so confusing.
