I have read quite a lot of books, but there are those that I will advise you to read everything, and there are also those that you should never read for anything.
I can definitely advise you to read such a beautiful book as the "alchemist" Paulo Coelho. Describe what is in this book, I will not, read the description and you will understand.
But there is a book that did not interest me a bit. And her name is "country of joy." Stephen's book is a book, who would think, right? As for me, all the books of Stephen are interesting in their own way, but this ... A novel with the sufferings of the main character from unrequited love does not interest me very much.
