I think it is a very fascinating way of moving magic from one person to another, and while it is pretty gruesome, I'm interested in what people can do with it.
I loved The Final Empire. I read it before knowing much about the Cosmere, and I had only been reading for about an hour before I went to the store to buy The Well of Ascension. I do also really like Yumi and the Nightmare Painter, specifically because of the romance parts. It reminded me of my girlfriend at some points. I guess I also like The Bands of Mourning a lot. I read that one in four days. I guess I really like all of them. I haven't read one I didn't enjoy.
You know, I'm not sure. They all seem kinda dangerous.
