Most of them hate the 'real' world, but Jess begins to question whether the digital world is 'perfect' after all. Back home, her sister Chloe's life-saving medication is getting ever more expensive. Determined to help, Jess risks everything by using skills forbidden in the cyber-world, only to stumble on something explosive. Something that will turn her whole world upside down.
