What is the one (or maybe two) qualities a book must have for you to pass it along to your best friend as a "must-read"?
Of course, the book depends on the person I am recommending it to. If it were my sister, I'd recommend every book I love; because she'll also love almost all of them! But that's not the same with my friends. I tend to read rather genre-specific books these days - mostly fantasy or science fiction. And they tend not to like them. So, for my friends to like the book, the first requirement is that the book does not belong to either of those genres!
Usually, what I tell my friends to be a"must-read " has a different or new or unique plot. Not like your usual mysteries, crime stories, classics, romances or horror stories. The last book I really forced my best friend to read was Life of Pi by Yann Martel. (Isn't this cover absolutely beautiful?) And the next book I am going to make her read is The Professor and the Madman by Simon Winchester.
