Momentum

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. 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.
