"Rollercoaster" is a fast-paced business narrative that chronicles one of the most dramatic periods in business history. It is the story of Chris Gent and Vodafone. Loved by the City as a brilliant dealmaker, Gent himself is often described by those who know him as affable and self-effacing. Yet he has somehow fostered a deeply engrained culture of ruthless ambition in those who run Vodafone in his name. But as the telecommunications sector has imploded, Vodafone has been swept along by bad news amongst accusations of poor acquisitions, over-investment and fat cat payouts for Gent himself. Trevor Merriden charts the dramatic rise of Gent and Vodafone and assesses the underlying forces driving the man and the company. He examines the turbulent recent history, of Gent's resignation, and asks searching questions about the future of the company.
