Emerald Fennell & Tristan Gooley at the Hay Festival

Emerald Fennell and Tristan Gooley will be appearing at this year's Hay Festival in Hay-On-Wye.

Emerald will be reading and speaking about her book Monsters on Sunday 5th June. A blackly comic tale about two children you would never want to meet. Set in the Cornish town of Fowey, all is not as idyllic as the beautiful seaside town might seem. The body of a young woman is discovered in the nets of a fishing boat. It is established that the woman was murdered. Most are shocked and horrified. But there is somebody who is not - a twelve-year-old girl. She is delighted; she loves murders. Soon she is questioning the inhabitants of the town in her own personal investigation. But it is a bit boring on her own. Then Miles Giffard, a similarly odd twelve-year-old boy, arrives in Fowey with his mother, and they start investigating together. Oh, and also playing games that re-enact the murders. Just for fun, you understand...

Tristan's talk about his new book How to Read Water: Clues, Signs & Patterns From Puddles to the Sea is on Tuesday 31st May. From wild swimming in Sussex to way-finding off Oman via the icy mysteries of the Arctic, Gooley draws on his own pioneering journeys to reveal the secrets of ponds, puddles, rivers and oceans. He shows us the skills we need to read the water around us. Gooley is the author of The Natural Navigator and The Walker’s Guide to Outdoor Clues and Signs. Chaired by Laura Powell, Features Commissioning Editor at the Daily Telegraph and author of The Unforgotten.
