The Fires of December Release Date: Everything We Know So Far

The Fires of December by Brandon Sanderson comes out on 8 December 2026. It's a standalone Cosmere novel framed as a tale Hoid has to share, following a young woman named December who sails upriver to warn a royal court that a plague is coming. It's also the most anticipated book with a confirmed date on our calendar.

That last point isn't hype. Of the 76 upcoming books with a confirmed date that we track, this one ranks number 1 by readers on Hardcover, ahead of 98% of them, with about 190 times the readers of the typical upcoming book. Cosmere fans, it turns out, are not a patient crowd.

When does The Fires of December come out?

The release date is 8 December 2026. Macmillan, the publisher, gives that same on-sale date on its own page ^[2]. Barnes & Noble lists the hardcover with the same release date too ^[3].

So there's a heroine called December whose book comes out in December. Someone in the publicity department deserves a biscuit.

Has the release date moved?

As far as the publisher is concerned, no. The one oddity is on Goodreads, which shows an earlier "first published" date for the book, and the page gives no explanation for the difference ^[1].

I wouldn't read much into that. Goodreads placeholder dates drift all the time, and the publisher and a major retailer agree with each other. If anything changes, it will show up on our calendar and the countdown will update.

What is The Fires of December about?

The official description calls it the next Cosmere standalone novel, with Hoid telling the story ^[1]. That framing matters: Hoid is the wandering storyteller who turns up across Sanderson's worlds, and here he's the one doing the narrating.

The tale itself is set in a forgotten land kept alive by rivers of demon blood, and those rivers come in colours. A young woman named December learns that a devastating plague is on its way, and nobody seems inclined to believe her. She sets sail up the River Violet to warn the king's court ^[1].

On the way, the blurb promises:

• incredulous royal officials
• twisted court intrigue
• a roguish count
• two new friends: a talkative priestess and a fledgling fashion designer

Barnes & Noble's version of the blurb puts it plainly: a plague is coming, and only December can warn the king's court in time ^[3].

A fledgling fashion designer as a sidekick in a plague story is the sort of detail that tells you the tone might lean lighter than a ten-day apocalypse on Roshar. I'm looking forward to finding out how that mix works.

Is The Fires of December part of a series?

It sits inside the Cosmere, Sanderson's shared universe, and on our list it's numbered as book 36 of The Cosmere. Macmillan lists it as "A Cosmere Novel" and gives its series as "Hoid's Travails" ^[2]. Goodreads files it as book three of Hoid's Travails ^[1].

Neither listing spells out which books count as one and two, so I won't guess. What both are clear on is that this is a standalone ^{[1] [2]}.

How long is The Fires of December?

That depends on whom you ask. Macmillan's page lists 384 pages ^[2]. Goodreads shows a 452-page hardcover ^[1].

Either way, it's short by the standards of a writer whose Stormlight books are often used as doorstops. Page counts before release often shift once the final layout is done, so treat both figures as provisional.

Has Brandon Sanderson said anything about it?

So far the official word is the publisher's description, which presents it as a new standalone novel set in Sanderson's Cosmere universe ^[2]. The Goodreads description appears under Sanderson's own name and leads with Hoid having a tale to tell ^[1].

Beyond that, there's nothing from the author I can point to with confidence, and I'd rather leave a gap than fill it with rumour.

The Cosmere so far: a spoiler-light recap

There are 30 published main books in the Cosmere on our list, spread across several worlds. You don't need any of them for a standalone, but here's the lie of the land, kept to premises.

Elantris

Elantris is where it started: a city of radiant demigods whose magic failed ten years before the story opens, and a princess, Sarene, who arrives for a marriage of state to find her prince has died. It's the 8th most-read Cosmere book on our list. The Hope of Elantris is a short story that fills in one of the gaps Sanderson left in the original.

Mistborn: the original trilogy

Mistborn: The Final Empire is the most-read Cosmere book of all, ranked 1 of 30: a heist against an immortal tyrant called the Lord Ruler, in a world where ash falls and no flowers bloom. The Well of Ascension (3rd most-read) and The Hero of Ages (4th) complete the trilogy.

Mistborn: Secret History is a companion story that its own blurb warns contains huge spoilers for all three books, so save it for after. The Eleventh Metal was written for a tabletop game and offers a little more on Kelsier.

Warbreaker

Warbreaker follows two princess sisters, a God King one of them has to marry, a lesser god who dislikes his job, and an immortal trying to undo old mistakes. Its magic runs on breath and colour, which makes it worth noting as a rivers-of-colour book comes along. It ranks 11th.

The Stormlight Archive

The Way of Kings opens Sanderson's biggest series on Roshar, a world of stone and highstorms, and is the 2nd most-read Cosmere book. Words of Radiance (5th), Oathbringer (6th) and Rhythm of War (9th) follow Kaladin, Dalinar and the returning Knights Radiant through a widening war.

Two novellas sit between them: Edgedancer, about Lift, a young Radiant who asked a goddess to stop her growing older, and Dawnshard, a sea voyage to a storm-shrouded island. Wind and Truth gives the Radiants ten days to prepare for a contest of champions with the god Odium.

Mistborn: the Wax and Wayne books

Set three hundred years after the first trilogy, The Alloy of Law brings railways, electric light and a frontier lawman, Waxillium Ladrian, to Scadrial. Shadows of Self, The Bands of Mourning and The Lost Metal carry Wax, Wayne and Marasi through terrorism, mythical artefacts and a shadowy organisation called the Set. Allomancer Jak and the Pits of Eltania is a comic short told by an unreliable adventurer, footnoted by his long-suffering steward.

Shorter works and other worlds

• The Emperor's Soul: a forger, Shai, has under a hundred days to Forge a new soul for an emperor.
• Shadows for Silence in the Forests of Hell: a homesteader in a forest of lingering shades, where you don't kindle flame or run at night.
• Sixth of the Dusk: a trapper on the deadly island of Patji, where birds grant magical talents.
• White Sand, Vol. 1, White Sand, Vol. 2 and White Sand, Vol. 3: graphic novels about Kenton and the Sand Masters of Taldain.

The recent standalones

This is the stretch closest in spirit to the new book. Tress of the Emerald Sea sends Tress to sea across spore oceans to find a sorceress, and it's the 7th most-read Cosmere book on our list, ahead of every Stormlight volume after the third. Yumi and the Nightmare Painter links two people from very different worlds, and The Sunlit Man follows a wanderer called Nomad on a planet with a deadly sunrise.

Isles of the Emberdark brings back Sixth of the Dusk from the earlier novella and sends him into the emberdark in a canoe with his birds.

Do I need to read the earlier Cosmere books first?

No. Both Goodreads and Macmillan describe it as a standalone ^{[1] [2]}. A young woman, a river and a plague is about as clean a starting point as Sanderson offers.

What you'll miss is the background on Hoid, who has been popping up at the edges of Cosmere books for years. Long-time readers will pick up the winks; new readers will just get a storyteller with a good voice.

If you want something similar beforehand, Tress of the Emerald Sea is the obvious pick from the blurbs alone: another standalone about a young woman setting off by ship against long odds. If you'd rather go further, the full The Cosmere reading order is on our series page, with every book in order and its date.

How do I find out the moment there's news?

With publication this close, the next things to watch for are a confirmed final page count, any excerpt or cover reveal, and that Goodreads date catching up with the publisher's. You can keep refreshing Goodreads, or let something else do it.
