My suggestion: Maybe we should not designate the book by Genre. Let's just list different kinds of books and then we'll choose from our list what will be the book for the month. The book suggestions must have a small incite.
e.g. The Alchemist by Paolo Coelho
Quote:
The Alchemist details the journey of a young Andalusian shepherd boy named Santiago. Santiago, believing a recurring dream to be prophetic, decides to travel to the pyramids of Egypt to find treasure. On the way, he encounters love, danger, opportunity and disaster. One of the significant characters that he meets is an old king who tells him that "When you want something, all the universe conspires in helping you to achieve it." And this is the core philosophy and motif of the book.
