Tyler and Copper Bower-two twins who couldn't be more different-have just moved with their single mom to a new home in Potterville, Ontario. Unbeknownst to their mom, the twins are wizards-in-training and are about to undergo a secret coming-of-age rite, led by their grandpa, that will grant them new powers, bringing them closer to becoming fully fledged wizards. Cooper is excited about the possibilities in store for them, but Tyler is worried that the more they practice their abilities, the greater the chance they will be found out. If regular people learn they are wizards, the brothers would never live in peace again. With this fear in mind, Tyler finds it difficult to trust others, while Cooper is eager to make new friends.Soon after the brothers start their new school, strange events begin to occur-entire classrooms are left in shambles, and students and teachers are frozen in fear. Not only that, but Tyler and Cooper sense that someone-possibly a student-is lurking in the shadows, watching them. Determined to figure out what's going on, they realize that without control over their powers, they might be in over their heads. And with Halloween approaching, when dark forces are at their most powerful, the stakes are higher than ever. Will the twins be able to prevent disaster on their own, or will they need to seek help before things spiral out of control?
