What Loki A Bad Gods Guide To Being Good Actually Is
The book you are looking for is Loki: A Bad God's Guide to Being Good, a short humorous novella by Brandon Sanderson that came out in 2024. It is set in his Cosmere universe and follows Loki, the former god of secrets, who has been imprisoned for millennia and is now trying to figure out what it means to actually do good things after spending most of his existence being devious. The story is told through a mix of narrative and faux-instructional passages, which is exactly the tone the subtitle promises. It is not part of the main Mistborn timeline, though it shares the same fictional universe. If you have never read anything by Sanderson, you will still understand the plot, but you will miss a lot of the background jokes about gods, magic systems, and how the Cosmere fits together. That is fine. It works as a standalone read.
Loki A Bad Gods Guide To Being Good
Here is the thing most people get wrong about this book: it is not a sequel to anything. It is a companion piece. Think of it as filler content between major releases, but well-written filler. Sanderson uses it to explore Loki as a character, who was briefly mentioned in Mistborn: Secret History and then in passing in several other books. The novella fills in gaps about what Loki did during his imprisonment and how he ended up where he is now. The format is intentionally uneven. Some sections read like a conventional story. Other sections are written as if Loki himself is giving you advice on how to be a decent person, which is where the humor comes from. The advice is terrible. That is the joke. He keeps suggesting manipulative strategies and then slowly realizing those are not good ideas. It is a self-aware comedy structure that works better than it should. I picked this up on release day and finished it in one sitting. The prose is light, the pacing is brisk, and the payoff at the end actually lands emotionally despite the silly setup. It is roughly 150 pages in most editions, so it is not something you commit to for weeks. You read it and move on.
Where to Get It
The book is available through most major retailers. Amazon carries both the paperback and the Kindle edition. Audible has an audiobook version read by the author himself, which is worth it because Sanderson does voices for the different characters and the performance is genuinely funny. Barnes & Noble, Book Depository, and independent bookshops usually stock the print version. If you live somewhere with limited shipping access, the Kindle edition downloads immediately and costs less than the paperback. There is no free legal version. Any site offering it for free is distributing pirated material. I do not recommend it because the quality of the file is often poor and you are undermining a writer who depends on book sales. Spend the money. It is cheaper than most meals.

What to Expect From the Story
Loki has been locked away for a long time. His punishment is supposed to be reform through service, which means he gets assigned to help people in ways that look like random encounters rather than direct divine intervention. The narrative tracks his attempts to follow the rules of his sentence while slowly figuring out what those rules actually mean. The supporting characters include a few familiar faces from the Cosmere who make brief appearances, but none of them dominate the story. The humor relies heavily on dramatic irony. You know Loki is not actually good. He knows it too. The gap between his intentions and his methods is where the comedy lives. Sanderson writes this without being mean-spirited. Loki is not a villain in this book. He is a flawed person learning on the job, which makes him easier to root for than you would expect from a god of secrets. One scene stands out. Loki tries to help someone by orchestrating a complex situation where that person discovers a truth on their own. It goes wrong in exactly the way you would predict. The fallout is awkward and funny and honestly kind of relatable. People do this in real life. We try to engineer outcomes for others and then act surprised when it backfires.
Pitfalls and Who Might Not Like This
This is not a dense novel. If you are looking for worldbuilding depth or intricate plot machinery, you will be disappointed. The Cosmere connections are surface-level. The magic system gets a mention but never any real development. The book assumes you already know the basics or do not care about them. That is not a flaw in the book itself. It is a mismatch between your expectations and what the book actually is. The tone will also grate on some readers. The instructional segments are written with a sarcastic edge that some people find grating rather than amusing. I personally found it fresh the first few times and slightly repetitive by the end. The structure repeats itself enough that you can predict the next section before it starts. That is a deliberate choice by the author to mirror Loki's own repetitive pattern of failed reform attempts, but repetition is still repetition. Another issue: the ending ties up Loki's arc but leaves several larger Cosmere threads hanging. If you finish this and then try to jump into The Lost Metal or another recent Mistborn book expecting all these threads to resolve, you will be confused. This book is a side story. It does not advance the main timeline in any significant way.
How It Fits With Everything Else
If you want to read this in order with the rest of the Cosmere, the recommended path is to finish the original Mistborn trilogy, then read Mistborn: Secret History where Loki first appears, then read this novella, then continue with whatever other Cosmere books interest you. Oathbringer and Rhythm of War also reference Loki indirectly, so reading those before or after this book will change how you perceive his role in the larger story. Some readers place this after The Lost Metal. That works too if you want all the major references to land. The book does not require prior knowledge, but having read at least some Cosmere material will make the jokes land harder and the cameos more meaningful.

Bottom Line
Loki: A Bad God's Guide to Being Good is a short, funny, mildly heartfelt novella that serves as character study more than plot driver. It is not essential reading for understanding the Cosmere. It is optional reading that most fans of the universe will enjoy at least once. If you already like Sanderson's humor and his tendency to write flawed characters who try to do better, this will probably work for you. If you are picky about pacing or prefer tightly plotted narratives, you might find it meandering. I would still recommend it. Just know what you are getting into before you start.
