Its supreme leader, The One Who Is The One, has banned everything they hold dear: books, music, art, and imagination. But the growing strength of the siblings' magic hasn't been enough to stop The One's evil rampage, and now he's executed the only family they had left. Wisty knows that the time has finally come for her to face The One. But her fight and her fire only channel more power to this already invincible being. How can she and Whit possibly prepare for a showdown with the ruthless villain that devastated their world--before he can truly become all-powerful?
