Prince Ash achieved the impossible and journeyed to the End of the World to earn a soul and keep his vow to always stand beside Queen Meghan of the Iron Fey. Now he faces even more incomprehensible odds. Their son, King Keirran of the Forgotten, is missing. Something more ancient than the courts of Faery and more evil than anything Ash has faced in a millennium is rising as Evenfall approaches. And if Ash and his allies cannot stop it, the chaos that has begun to divide the world will shatter it for eternity.

Sequel to: The iron raven.
