A book this long should count as 3 books for the reading challenge! 
 More than a thousand pages of setting... and I enjoyed each and every one of them! At first, I struggled with the info dump: desolations, heralds, radiants, spren, stormlights, shardblades, lashings, surgebinders, soulcasters, fabrials, oathpacts, names that looked the same, voidbringers, vorinism, countries, races. All thrown at you from the start, making no sense at all. 
 Many things still don't make sense after a thousand pages, but the basics are covered and it makes you want more. So be prepared for a book which introduces the world of Roshar, the main characters and the basics of the plot, but leaves a lot of questions still unanswered. 
 Amazing worldbuilding as always. I want to live in Brandon Sanderson's head for a while... but preferably not during a Desolation. 
 (view spoiler)[ After reading 7 cosmere books I still don't understand how all the pieces fit together, especially Hoid (hide spoiler)]
