Majellan grabbed Mercy by the arms and pulled her close to him. She could feel his hot breath on her face and his seething anger. "If you betray me again, pup, it shall be the last thing you ever do," he growled.

KYRA MURCH has disappeared and it's up to her friends Coyne and Mercy to find her. But Coyne is reeling after the Raturro's invasion of the Plains, and Mercy is being held hostage in Thane's Reach. When Majellan discovers the ancient city of Tethys far below them, he forces Mercy to use the Adularia Stones, unleashing an ancient and unstoppable darkness.
In this final installment of the exhilarating series, Kyra and her friends may have to choose between the world they love, with all its magic, and saving their warring nations.

Peace always has a cost. The only question is: will Kyra be ready to pay it?
