Thorn’s latest mission: protect the prince of Cyre, a monarch in name only since his country was destroyed by the Mourning. But in that same cataclysm, seven cities of the Feywild—the feyspires—were trapped on the plain of Eberron , a concurrence the eladrin who rule the feyspires insist is no coincidence. They insist that with the right pieces they can repair the devastation of the Mourning. All they need are a few missing –one in the heart of a mysterious Cyran soldier and one that’s lodged in Thorn’s spine, carrying the soul of the Angel of Flame.
