Kelsier is a half skaa half noble mistborn. He escaped from the Pits of Hathsin, where the Lord Ruler sends lawbreakers. He made it back to Luthadel, the Empire's capital, where he gathers a crew of underworld allomancers that he knew before he was sent to the pits. He also finds Vin, a small street urchin, who has been living her life in her own crew of normal underworld thieves. She is constantly paranoid of betrayal and attack. Together, Kelsier, Vin, and the other forbidden allomancers plan to overthrow the Final Empire.
Overall this book was very good. It created a new world with depth and it had a good amount of magic, noble politics, and underworld action. However, it was very difficult at times to imagine some of the characters. I could see Kelsier, Vin, Hammond, who is part of the crew, Sazed, another friend of Kelsier's, and some of the nobles. Most of the characters never got an image. I could understand them; their actions, emotions, and character were fine, but I could not see them. I also had the Inquisitors, elite law enforces with spikes sticking out of their eyes, looking like Darth Maul from Star Wars, and I am pretty sure they aren't meant to look like that. Sazed, who was a good character for the most part, said "I think" so many times. He is a very thoughtful person, but he does not need to say that after every statement.
Despite its shortcomings, Mistborn gets a 4.9. It had a good mix of different things going on, such as the parts of the story concerning the nobles as opposed to the parts concerning the rebellion. Most books only really have one. The ending of the story was somewhat unsatisfactory. It was like a really good cake. Deep chocolate with light, fluffy frosting that you enjoy every bite of. There is something, however, that makes it a little hard to eat, perhaps it is too thick or too sweet (the book is not too "sweet" or too good, but the feeling I had while reading it is very similar to the feeling you get when eating something that is too sweet), and when it's over, you're not quite left with the feeling you had hoped for.
