Momentum - Saci Lloyd

London, the near future. Energy wars are flaring across the globe - oil prices have gone crazy, regular power cuts are a daily occurrence. The cruel Kossak soldiers prowl the streets, keeping the Outsiders - the poor, the disenfranchised - in check. Hunter is a Citizen: one of the privileged of society, but with his passion for free running and his rebel friend Leo he cannot help but be fascinated by the Outsiders. So when he meets Outsider Uma, he is quickly drawn into their world - and into an electrifying and dangerous race to protect everything they hold dear.
