Alara's incredible gaming skills bring her to the attention of Estrella's leaders. She is chosen to go on a dangerous mission to London Under, the original older, long-deserted and distrusted city on top of which Estrella (the Star city) was built, to gather 'vital' intelligence. Estrella is the perfect society, an immaculate, sanitised, connected environment where everything is channelled through the digital medium. There is no dirt, no pain, no disease, no natural world, even feelings like boredom are frowned upon and discouraged. Alara is dropped down to London Under and into a "new" world which bewilders her and disorientates her. How will she survive in a society where noise dirt and sometimes pain are everyday experiences and where food is not synthetic and tastes real? Will she accomplish her mission? Who can she trust? How will she get back to Estrella and her family and her life without worry?
