Hildr Stormsworn: When the oath breaks, the storm answers.

A broken oath. A dying world. A woman who refused to disappear into either.

In a world governed by the Ei m l - the ancient compact between sworn word and physical consequence - oaths are not metaphors. They accumulate in the body. They silver the hair and frost the hands and press against the sternum like a building deciding whether to fall. When Hildr Ei ard ttir broke her oath to her Jarl at Vindheim's fall, the world recorded it. Three years later, it still remembers.

Hunted by Magn s the Pale, the Ei v r r's most methodical warrant officer, Hildr has spent those three years surviving on the border coast, alone in the particular architecture of a solitude she built herself. Then a wolf walks out of the winter tide, and everything that was settled becomes complicated.

The wolf is Sk ll, old in ways that do not map to years, diminishing in ways he cannot fully explain, and for reasons he will not discuss, he has chosen her. The skald rir the Unfinished follows - young, covered in rune-tattoos from jaw to collarbone, determined to witness and record whatever Hildr's story turns out to be. Others join: Sigr r, whose oath-cost has been living in her left hand as ice since the sealing she almost did not survive; Brynja, a J rnm rk-trained smith with burn scars and an iron eye; Gunnar Tv auga, who has one eye of glass and the particular economy of someone who has already said everything worth saying.

The Fimbulwinter is in its third year. Skei -rifts are splitting through the landscape, draining the world of living purpose and leaving behind the silhouette of what was there - dead-white forests, emptied rivers, air that presses equally from all sides. Someone is causing the rifts. His name is Ei stormr. He has been doing this for fifteen years, weaponizing the same oath-energy that the world was built on, feeding it into a system that is slowly killing everything. He is not stupid. He may not be entirely wrong. And he is coming north.

The journey is to Yggdrasil's root. To the Well where oaths began and where, perhaps, one can be spoken that will answer what Ei stormr has done. But to get there, Hildr will have to reckon with the warrant on her head, the man pursuing her, the wolf who is running out of whatever it is that keeps him present in the world, and the oath she broke three years ago - what it was, what it cost, and whether the woman who broke it is capable of speaking one that holds.

Hildr Stormsworn is an epic Norse-inspired dark fantasy told through the chronicle of rir the Unfinished - spare, precise, and unsparing about what it means to carry a choice you cannot put down.

Perfect for readers of Katherine Arden, N.K. Jemisin, and Joe Abercrombie.
