Actually, I don’t choose books randomly. Every time I decide to buy a book or a novel, I choose it by its story. It rarely happens that I pick up a book without knowing what it talks about. Because of that it doesn’t happen to regret buying a specific book depending on its cover.
On the other hand, I may buy a book according to its title, titles actually attract me, I love titles that include cities names or months names, but still don’t make me take a rush decision about a book. I always read a brief introduction about the book, its idea, its story, and one of the important fact is the author’s name.
