In the drowned kingdom of Virelund, where the sun hasn't risen in a hundred years, the Hollow King stirs once more. His soul was bound in chains of moon-iron and buried beneath the roots of the world - but now those roots are rotting, and the dead whisper in the language of smoke.
Eira Blackvale, a disgraced noble with blood on her hands and a shadow that moves on its own, is drawn into a crumbling empire's last desperate gamble. She is tasked with retrieving the Severed Crown - a cursed relic said to hold the last light of the dying gods. But others seek it too: witches who bleed ink, knights whose armor grows like bone, and a boy-king with fire in his veins and voices in his head.
As ancient horrors rise and forgotten pacts awaken, Eira must confront a truth deeper than the void - that some thrones are meant to be empty, and some kings never die.
