Ten years of study, ten years of life for the chance to grasp the secrets of magic and become a powerful witch. I broke all the rules and ran away from the one who made me the best. And now I’m forced to break another—my own—rule: return to the place where he can catch me and make me pay for debts from the past. I can only hope in myself. I am Diana Teynon—the best magic-guard in the territory of the United Kingdoms, of course, except for my teacher. But I swore never to remember him.
