Fifteen-year-old Jaylon is a member of the east London Blake Street Boyz gang. His every life choice is subject to its laws, right down to what chocolate bar he eats. To move up to the senior level, the Olders, he must stab someone from a rival gang. He's not keen, but it's not a choice "kill or die".Turf strongly resembles last year's Pigeon English but with a slightly older cast, and instead of a mystical pigeon, a tramp called Leo who dispenses crazy wisdom. It might just be all the pills and weed, but soon Jaylon is talking to people who might not be there, having visions and being lectured by the hologram of Jesus that hangs on his aunt's wall. The "turf" he fights over takes on a spiritual dimension.Lucas cleverly contrasts the banality of school life with the brutal code of the streets as Jaylon ricochets between them towards a nail-biting finale. An exhilarating, tragic tale and a terrific debut.
