Book excerpt: Mr Nasty charts the rise, fall and ultimate redemption of a wannabe player in the global narcotics business. From humble beginnings on the streets of London's East End, Cameron White rapidly ascended the drug ladder of London's club scene before notorious local criminals forced him to move to the US. There, he soon found himself aboard a cocaine-fuelled roller-coaster ride, transporting him from encounters with psychotic, crack-dealing Jamaicans in New York to luncheons with Hollywood's glitterati. The American adventure was to reach its inevitable conclusion in a drive-by shooting in the barrios of LA.Back in London, a dull nine-to-five existence did nothing to quell White's narco-inclinations. Cue a chemical vacation in Thailand and an effortless metamorphosis from recreational drug user to fully fledged smack addict in Berlin. White's eventual wake-up call came after he robbed some innocent tourists to feed his heroin habit. Stunned to realise how low he had sunk, he was determined to get clean and his gold-star efforts at rehabilitation were rewarded with an opportunity to start again in Australia. Faced with temptation once more, White's good intentions were to prove short-lived and he slid into the murky world of substance abuse in Sydney. But this time things were different and a gradual but life-defining epiphany rescued White from the edge. Mr Nasty is a thrilling yet cautionary tale of a decade lived within the narcotics underworld. Illuminating both the exciting and destructive sides of such an existence, it is ultimately a testament to how a strong will can sometimes overcome the lure of vice and break the chains of addiction.
