You can’t judge your book by its cover. Sometimes the cover means something different of what the book is talking about. Maybe you don’t like the cover but when you read the book you find it amazing and also maybe you like the cover but the book itself when you read it you don’t like it.
When you see a book sometimes the cover attract you so you feel that you have to read that book sometimes you like it and sometimes no.
So never judge a book by it’s cover.
