Bands of Mourning definitely deserves 5 stars and it was my favourite of all the books with Wax and Wayne and I had more fun reading it than the books with Elend and Vin. The only book I like more is The Final Empire (except for the ending) because Kelsier is still my favourite character, I don't think anything can change that. He was just too awesome. 
 The story is definitely getting more interesting. So many things happened and we got some answers, but the book raised even more questions. (view spoiler)[ 
 For example: 
 What is that red thing that made even Sazed afraid? 
 What are the creatures with the red eyes? 
 And was that really Kelsier in the end?...I hope is was him. Though I was fooled once, so I'm careful now. (hide spoiler)] 
 I just wish I could read the next book today! 
 I really like the characters. Wax and Wayne are my favourite, but MeLaan and Steris are also great. MeLaan provides a lot of humor and Staris...I really do like her much more after this book. She is very intriguing and she did many cool things that I totally wasn't expecting. (view spoiler)[ And I was so happy in the end. It really looks like she might be just perfect for Wax. (hide spoiler)] 
 I have to say that B. Sanderosn really worried me there near the end. I was an emotional roller coaster...one minute I was looking for the tissues and the next I was smiling like an idiot...(view spoiler)[ I really thought that Wax was going to die and I wasn't ready for that. (hide spoiler)]. 
 I have to say that Wayne was my favourite character from the second Mistborn trilogy until Bands of Mourning, but I think I liked Wax just as much in this book. I liked him in the first book too, but he could be boring at times. But gradually, he grew on me. (view spoiler)[ Saving that kid and things like that certainly made me like him more (hide spoiler)]. But I really wish that B. Sanderson could give this guy a break, so many bad things happened in his life. 
 Well, now I need to try to wait patiently for the final book.(view spoiler)[But please, let it be a happy ending this time, I don't want almost everybody dead in the end like in the previous books:(... (hide spoiler)] 
 In the meantime, I still have The Secret History to read:)
