John Blashford-Snell is one of the world’s most renowned and highly respected explorers and authors. A former British Army officer, he is amongst the last of a generation of true explorers; having pioneered new methods of exploration and discovery.  He has documented unchartered territories, nature and peoples. Over his extraordinary life of adventure, John has conducted more than 100 expeditions for the purpose of scientific research and community aid. From exploring the Blue Nile in Ethiopia for Emperor Hailie Selassie, to delivering a grand piano to the Wai Wai in Guyana; discovering mammoth-like elephants in Nepal. And from founding the UK charity Just a Drop, establishing Operation Raleigh (now Raleigh International), and the Scientific Exploration Society, all of which still continue to do great work today. In the 2019 he was appointed a CBE for services to both scientific research abroad and to young people in the UK.

Pamela Hartshorne began writing novels to fund a PhD in medieval history, and has since written over 80 books, both fiction and non-fiction. Here she will explore her 'time slip' novels, based on her research of Elizabethan York, and the challenges of treading a fine line between historical accuracy and a compelling story.
