About This Book
Xar, a Wizard boy with no magic, races through the dark forest, desperate to find the power he’s never had. Meanwhile, Wish, a Warrior girl hiding a forbidden magical object, sneaks through the shadows, determined to keep her secret safe. Suddenly, their paths collide—and something ancient begins to stir in the dungeons below...
