James Patterson's Witch & Wizard: The Battle for Shadowland #4
Back at Garfunkle's, Whit finds a spell that might counteract the Breach Device being used by the New Order to try to destroy the resistance. Whit joins Wisty and the other kids on the rooftop in order to cast a "curse" spell that may help tip the odds in their favor. Heeding the call to arms, the young rebels encounter scores more troops entering Shadowland. As this huge battle rages on, the future of our heroes lies in the balance as this action-packed first adventure reaches its climax.
