This book me forever to read. It's not just that it's a large book, coming in at 541 pages. It's very information dense, with a whole new world being built. I found that I enjoyed it most when I read it in 20-50 page intervals. 
 Sanderson has built this amazing world with these wonderful, flawed, human characters, and given them this very intricate magic system to work with. I wanted more. I wanted to know what happened at the well (I think this is what book 2 is about?), I wanted to know about the darkness. I wanted to know just how common Mistborn really are. I wanted to learn more about the Inquisitors and the skaa. I think, if I'd gotten my way, this book would have been ten times as long, and because of the way Sanderson writes, there'd STILL be questions. The questions are what keep you reading, though. You need to know what's going to happen. There really is no walking away from this book once you start it. 
 I look forward to reading the rest of the series... once I clean my palette a bit and read five or ten other books that don't take weeks to read. Such an amazing book, though, I highly recommend it to fantasy lovers.
