Synopsis

For seven years, Lyanna drew only white Moonblooms—until the eighth, when she pulled the red Dragon's Breath. But her cruel fiancé wasn't the one who came. The kingdom's deadliest dragon rider arrived on his black beast, knelt before her, and took her away from everything that ever hurt her. Now the man who betrayed her can only watch as she rises.
