Stephen Venables is one of Britain's most successful mountaineers. Here he touchingly talks about the brief but couragrous life of his son Ollie, who battled autism, Leukaemia and a brain tumour before dying at age 12. Despite all his challenges, Ollie was a lively, playful and mischievous child, and generated huge amounts of laughter. This is a beautifully written and extraordinary personal testament.
