"As I sat cradling the man's head, with his blood and brains sticking to my hands, I heard a voice - my own voice. It was asking me something. Asking how I had ended up like this, desperate and lost among people who thought nothing of caving in a man's head and then standing back to watch him die." Nick Bullock was a prison officer working in a maximum-security jail with some of Britain's most notorious criminals. Trapped in a world of aggression and fear, he felt frustrated and alone. Then he discovered the mountains. Making up for lost time, Bullock soon became one of Britain's best climbers, learning his trade in the mountains of Scotland and Wales, and travelling from Pakistan to Peru in his search for new routes and a new way of seeing the world - and ultimately an escape route from his life inside. Told that no one ever leaves the service - the security, the stability, the 'job for life' - Bullock focused his existence on a single goal: to walk free, with no shackles, into a mountain life. Echoes, his first book, is a powerful and compelling exploration of freedom - and what it means to live life on your own terms.
