I've started this book back in august 2010, then I lost it, then a friend found it, then he gave it back to me about a month ago; I've read about 3/4 last year and a quarter in the past few days, and that's definitely not a good way to read a book.
I liked it a lot. It's not too slow, or heavy, or difficult as I thought it would be, and I'm actually curious to read more (the Bene-Gesserit! the Fremens! the Empire! so many things I want to know more about!)
