The Oathbreaker's Shadow

15-year-old Raim lives in a world where you tie a knot for every promise that you make. Break that promise and you are scarred for life, and cast out into the desert. Raim has worn a simple knot around his wrist for as long as he can remember. No one knows where it came from, and which promise of his it symbolises, but he barely thinks about it at all. But on the day when he binds his life to his best friend (and future king) Khareh, the string bursts into flames.
