Mistborn: Secret History (Mistborn Saga)By
A companion story to the original Mistborn trilogy, from #1 New York Times bestselling author Brandon Sanderson
Warning: this secret history contains HUGE SPOILERS for the original Mistborn trilogy, as well as very minor spoilers for the The Bands of Mourning.
Mistborn: Secret History builds upon the characterization, events, and worldbuilding of the original trilogy. Reading it without that background will be confusing.
In short, this isn’t the place to start your journey into Mistborn. (Though if you have read the trilogy—even if it's been a while—you should be just fine, as long as you remember the characters and the general plot of the books.)
Saying anything more here risks revealing too much. Even knowledge of this story’s existence is, in a way, a spoiler.
There’s always another secret.
