This is the third title in the brilliantly funny new series from the author of 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! Sink your teeth into Justin and Daniel's third wild adventure!
