A luminous journey through a thousand years of folklore and English history.Once upon a time in a Hertfordshire field, an ancient yew tree hid a dragon hunted by a giant named Piers Shonks. Today, the dragon and its slayer are the survivors of an 800-year battle between rural legend and national record, storytellers and sceptics.In this brilliant and lyrical history, Christopher Hadley journeys from churches to tombs to manuscript margins, to explore history, memory and legend, and the magical spaces where all three meet.
