Elli Tollet and Lance Poole are commandeered by the enigmatic Lyn Sayer, the pilot of a military helicopter, and embark on a dizzying time-travelling journey, meeting a cavalcade of characters, including Olwen, a green dragon. Set in a variety of times, but focussed in the Cheshire countryside, The Edge of Doom is rooted in ancient stories, and leads eventually to the sandstone hill of Alderley Edge, a place of mystery, where legend and history meet and where King Arthur is rumoured to sleep with his knights. The first of a trilogy - to be followed by The Dark Space and New Found Land.
