description: In the near future energy wars are raging across the globe blackouts are a regular occurrence and the privileged Citizens and the desperate Outsiders of London live very separate lives. Hunter is a Citizen whose father works for the government; yet he cannot help being fascinated by the Outsiders' ingenuity and in particular their mastery of free running. But when he meets Uma an Outsider he is quickly drawn into her world and finds himself racing against time  and against the government's cruel Kossak soldiers  to protect everything the Outsiders hold dear.
