And how can she fight for this virtual world when she's got a whole real life to keep up with: her family (though she could do without her mom's annoying cat) and her best friend, Eric. Things get even weirder when Izzy loses a life while inside the game, and she starts to worry about what might happen if she gets a Game Over for good"--Back of cover.
