From USA Today bestselling author Sarah Hawley comes the stunning conclusion to her darkly enchanting Shards of Magic series following Servant of Earth and Princess of Blood.

Princess Kenna of Blood House has decided who to support as the next ruler of Mistei, but one wrong move shatters the fragile truce of the Accord and plunges the kingdom into civil war. In the chaos, hundreds of faeries lie dead, and Kenna and the two rebel princes are captured.

With all other potential rulers imprisoned, two faeries crueler and more ambitious than even the late tyrant king claim the throne. Kenna is sure if they don’t kill her first, her guilt will. Her misstep could have lost the war.

But Kenna will never give up, no matter what horrors the enemy inflicts on her. Not when her house is looking to her for a brighter future. Not when she has finally found someone who loves her just as fiercely as she loves him. Yet with every blow she is dealt, the limits of how far she is willing to go to win the war get pushed further and further. In striving to transform Mistei for the better, Kenna risks losing her greatest strength—her humanity.
