Although this show fits more comfortably in a world of superheroes than one of wizards, its group of young, talented protagonists hearken back to Rowling's books. When a group of high school students find out their parents are actually secret supervillains, they must band together, hone their powers, and investigate what their parents are really up to. (Think Harry's crusade against Snape in Philosopher's Stone, but take it up a few notches.)
