Toby, Pete, Lorna, and Emily are just average kids-until they stumble upon a Web site that turns them into real heroes. Hero.com allows them to download flying, invisibility, or teleportation abilities, and suddenly, Tobys rivalry with his sister, Lorna, and Petes trouble with Jake Hunter, the school bully, dont seem so bad! But when the supervillain Doc Tempest kidnaps Tobys and Lornas mom, will they be able to combine their powers to fight evil and bring their mother home? Of course, little do they know that Villain.net is out there too, recruiting teens for the other side. . . .
