Book excerpt: Surfing the net during a lightning storm has amazing consequences for a group of teenage friends. Superhero powers are theirs at the click of a mouse! Trouble is, they don't know what the powers will be until they try them out . . . But super powers carry super responsibilities. When a weather-altering, world-conquering supervillain kidnaps their mum, they have to decide: save her . . . or save the world! 'Rise of the Heroes' is the first book in the brilliant new series 'HERO.COM' - the perfect antidote to the anti-series 'VILLAIN.NET', also by screenwriter Andy Briggs. Which side are you on?
