Arcanum Unbounded: The Cosmere Collection is finally here. This is a big, 670+ page book, with a ton of stuff. This has every single cosmere story that has been published outside of the main novels in one convenient collection. It has: The Hope of Elantris, The Emperor's Soul (which is incredible), The Eleventh Metal, "Allomancer Jak and the Pits of Eltania, Episodes 28 and 30", an excerpt from White Sand (both graphic novel and from prose), Shadows for Silence in the Forests of Hell, The Sixth of Dusk, and, for the first time in physical print, Mistborn: Secret History. That's a ton of value, just considering Secret History and Emperor's Soul.
But that is not all. Its main headline feature is a large, 40,000 word long Stormlight Archive novella: Edgedancer. It's a novella about Lift, of course, and covers her story after we saw her interlude up until the end of Words of Radiance. Not only that, but Arcanum Unbounded has some crazy cosmere information--essays from the author of the Ars Arcanum, Khriss, on each of the star systems--and star charts.
