I spent three weeks every Summer on Sark when I was a child. It is a truly magical place with its dramatic coastline, secluded beaches, hidden caves and dark, star-lit skies. I have been lucky enough to travel widely since I left the Channel Islands nearly twenty years ago but Sark remains my favourite place in the world. I have made use of its stunning scenery and unique history as a back-drop for Dark Sky Island but of course, the events and the people depicted in this book are entirely fictional.
