In a world with two suns, Tesni Kendrick has been taught to fear the blue sun and the people it shines over. In the South, the Wilde can harness the blue sun's power to perform great and terrible feats of magic. Tesni makes her home in the North, where the Wilde are the enemy, the blue sun doesn't shine and magic doesn't exist. Or at least it's not supposed to. For five years, Tesni has hidden her ability to wield magic and suppressed her powers. But when her father, the king's most loyal general, captures a group of Wilde men, Tesni's curiosity gets the best of her. From a handsome Wilde boy, she learns there is more to her magic than she ever imagined. Tesni's quest for knowledge--and the consequences it brings--takes her on a journey to the Wildelight, where the blue sun shines in full force and magic runs rampant. Can she learn to tame her magic from a people as wild as their name?
