Endless thanks to Karen Sullivan, who saw the potential in this story, and everyone else at Orenda Books for their tireless work and dedication. Thanks to Phil Patterson and all at Marjacq for their unstinting support. I also owe a debt of gratitude to Creative Scotland, for their belief in this book and their financial assistance. Thanks to everyone who has supported my writing over the years, it would be impossible without you. And loads of love, as always, to Tricia, Aidan and Amber.
