Windrider: Book 2 Masters of the Elements (Volume 2)

"Leave singing to the Hag to Fifth Ranks, lad, if you don't want to end up a witless madman shrieking to the storm from a cell in the Tower of Winds." Good advice, all in all. Sheshan ak'Kal lives to regret that he did not heed it, for Sheshan sings to tame the winds. But in a moment of rage, he falls prey to Wind's insane sister, the Hag. His song is lost, and now the Hag stalks him like a jealous lover. Unless he finds within himself a new song, the Hag will ravage the world and steal everything Sheshan loves.
