10­-year-­old twins Ethan and Emmy’s parents have never told their kids what they do for a living. Then just before Halloween, while their parents are away on an emergency business trip, Ethan, Emmy, and their best friend Jax discover a HUGE secret: could the twins’ parents actually be . . . witch hunters? Meanwhile at school, a new team of glamorous lunch ladies arrives on the scene, serving meals that taste way too good to come from a school cafeteria. There’s only one logical explanation: they’re witches, and the meals they serve are spiked with a dangerous potion! Why have witches come to Roosevelt Elementary? Where have Ethan and Emmy’s parents gone? Can it be a mere coincidence that their parents left just as the witches arrived? Whether they’re ready or not, Ethan and Emmy have only one option if they want to save their school and find their parents: become witch hunters themselves.
