A labyrinth only three can enter.
An angry war god out for vengeance.
Is she the heart they thought she was-or something more?
Seeking the ancient relics whose power can keep the fury inside her at bay, Princess Alexandria and her friends have left their loved ones behind in search of a labyrinth hidden deep in the mountains. When they discover a blood-red wall of stone, they must rely on their natural strengths-and each other-in order to gain entry.
As Alex, Edith, and Michael navigate a confusing network of underground passageways, the labyrinth tests them each in turn. But if they ever want to return home, Alex must make a choice that will change the lives of everyone she's ever cared about.
Meanwhile, Prince Aaron, her husband and king of Datten, is still reckoning with the curse that almost cost him everything. Sorcerers from the Forbidden Lands continue to attack, and he's not sure if Alex will ever be able to trust him again.
In order to protect his kingdom and show Alex he's changed, Aaron forms an uneasy alliance with Gryphon, the hot-headed sorcerer who is fated to rule with Alex when Aaron's mortal life comes to an end-and the only sorcerer powerful enough to train her for the battle to come.
But Gryphon is fighting a secret battle of his own, and when a dangerous figure from his past shows up demanding vengeance, he uncovers a truth that's remained hidden from everyone-even Alex.
As the sorcerers and mortals join forces to protect their queen, Alex's true identity threatens to change everything, and the fury continues to grow stronger. Who will commit the final betrayal?
