Really astonished book!!!! 
 First, the rules in this fictional world is totally insane. 
 Second, it's easy to get into those characters. And we will get their feelings more deeply in my minds. 
 Third, each twists come so quickly that it won't make me feel boring. 
 Forth, all the scenes in the plots are so vivid. Sometimes I feel that I'm part of them and I'm going to be unwinded in few days. 
 ...... 
 (Actually, there are more brilliant parts in this book. I just point out some of them.) 
 I didn't expect I will like this book at first. But as I've finished it, I can't stop telling anyone how deeply am I in love with Unwind.
