The prose flowed nicely. It was never a struggle. The audiobook had a great narrator. 
 Outside of that, I found this book very "meh". I really enjoyed Final Empire, and both of Sanderson's Stormlight Archives books, but Well of Ascension completely fell flat for me. 
 I didn't believe the relationship between Eland and Vin AT ALL. Sanderson did a great job of telling us that they were deeply in love, and explaining the reasons why, but at no point did they show it. I understand that Sanderson didn't want to write a romance, and that's fair enough, however when both of the main characters' main motivations and internal conflicts are the love they have for each other... It didn't work for me. 
 For some reason, I always notice the power levels of different things in a book, and when they're not consistent, it irks me. Vin was all over the place when it comes to how strong she was. 
 And the way Vin defeated (view spoiler)[Zane? Absolutely ludicrous! Atium clearly shows the future. Not what the other person think they're going to do. If it showed what the other person thinks they're going to do, then you wouldn't see the future image of anything once it had left the person's hand, but we regularly see coins flying around the place with their future images being visible to the Atium users. So the way Vin killed Zane was pure deus ex machine, and poor writing. Sanderson even acknowledges it in the text as Vin realises it. He wrote himself into a corner, and I was 100% unsatisfied with the way he got himself out of it. (hide spoiler)] 
 The ending didn't do much for me due to the above spoilered reason, and my lack of belief in the central romance. While I enjoyed Final Empire, I wasn't happy with the way it ended, and now I'm unhappy with the ending of this book... Unsatisfactory endings do not work for me. I am losing confidence in Sanderson as an author to leave me in a good place at the end of the next book in this series to the point that I might not read it. I'll definitely leave it for a while.
