The Thrill is honestly nothing more than the flashback sequence from Oathbringer by Sanderson. You can read my review on the full book here.
I was a bit bummed seeing this. It’s not new content. It’s not an alternate universe. It doesn’t provide new information. Sanderson is my favorite author in the game these days, and I’m always excited for new material. I don’t even mind re-reading it. I’m currently re-reading The Way of Kings as a way to get ready for the new Stormlight book. For people who haven’t tried any of his work (if they exist), this is a nice introduction. I’m a huge Dalinar fan, and this arc is wonderful. I just wish I had new Sanderson rather than stuff I’ve already paid for and enjoyed.
Thanks for reading
