From his career in speedway to his influential role in protecting some of the world's most endangered big cats, Peter Sampson's life is one of adventure and passion. This extraordinary biography, written by Tim Ewbank, takes readers on a thrilling journey through Peter's multiple careers - each more unpredictable than the last. Born in wartime Britain, Peter Sampson defied the odds from an early age. Leaving school at fifteen with no qualifications, he carved out a remarkable path, first as a fearless speedway rider, then as a successful transport operator, before embarking on his most profound mission - wildlife conservation. As the founder of the Big Cat Sanctuary and Hertfordshire Zoo (formerly Paradise Wildlife Park), Peter has dedicated decades to rescuing, breeding and protecting some of the planet's rarest species. With a foreword by Dame Judi Dench and conservationist David Mills MBE, this book is packed with fascinating stories: from meeting royalty and prime ministers and becoming a local councillor to rehoming a pride of lions from Ukraine. Told with warmth, humour and an unshakable commitment to making a difference, Peter's story is underpinned by the spirit of his characteristic motto: 'Keep happy, keep smiling'. Nothing's Impossible is a must-read for wildlife lovers, thrill-seekers and anyone inspired by a life truly well-lived.
