The epilogue. The epilogue. 
 I was slightly nervous about getting into this because I adore the original trilogy so much, but it didn't disappoint. It was definitely very different in atmosphere -not as dark in some ways, though morbid enough in others- but reading about the way the world had progressed and developed over time was brilliant. The magic system in this series is one of my favourites and the introduction of different Allomancy/Feruchemy combinations made it even better. 
 Every mention of characters and events from the original trilogy had me all excited and, at times, oddly sad. I loved them all so much and hearing them spoken about in the past tense, as if they were these mythical figures (I guess they were, weren't they?) was so strange. (view spoiler)[Any time anyone mentioned Harmony, I got emotional about Sazed. (hide spoiler)] I was worried I wouldn't like the new characters as much, but they didn't disappoint me either - scroll through my status updates and try to guess who my favourite is l mao 
 (view spoiler)[I wasn't sold on Miles, really. His twinborn combo was cool, but he felt very... cliche, I guess. Could have been worse, though! (hide spoiler)] 
 (view spoiler)[There were several mentions of Ironeyes and every time I was all "Marsh?! MARSH?!" and then the epilogue... 
 "... but he does my brother's work, and that is something I feel inclined to encourage." Poor Marasi. What a way to top off her day. Made my day, though. B) (hide spoiler)] 
 This book was just a lot of fun. If you enjoyed the first three books, you'll enjoy this one.
