The story is great, the processing of the book is not, unfortunately. As Anna has already mentioned, the paper is low-grade and partly missing letters. Not per se interferes with the reading all too much, because you know basically what word is meant. Just take the one course, the "reading experience" ... a good story should also presents accordingly! For this reason, I forgive the book "only" 4 stars.
Ps: Even if you've already seen the movie, you should be sure to read the book, regardless of whether you liked the movie or not. I found the film bad, really bad ... And after I read the book, I wonder how to make a film of such a good story so incredibly weak. If you too have not liked the movie, you get the picture book nevertheless give a chance, it's worth it!
