'Diving was a boys-own adventure, a jump into the unknown, full of devil-may-care attitudes. It welcomed you with one hand and cast you asunder with the other. It was a hideous bitch goddess and it drank the blood of the unprepared.'After an ordinary childhood, Hugh 'Obi' O'Brien's life has been surprising. What took this sporty country boy from Sydney boarding school to directionless youth to navy clearance diver, slipping undetected through deep waters to defuse mines and dismantle bombs? Upping that level of adrenaline, Obi joined the Special Forces counterterrorism unit TAG (East) - no picnic. In a memoir full of eye-popping anecdotes, he colourfully recounts this wild ride. He reveals the painful transition from military life to his days risking 'spaghettification' on underwater construction projects to private security work - pirate-hunting in the Red Sea and tearing along the world's most dangerous roads in the Middle East.Undaunted is for anyone who's ever dreamed of taking a high-action, alternative route through life. This is an engaging and unexpected account by an operator at once tough, whimsical and funny, and always brutally honest.
