Why do we read books, write books, talk about books, review books, and give books away? Dig deeper and we realize a passion for books is not just a stage in our lives but a life-long journey of eminent worth. Books provide sustenance like food. They immerse us in cultures we know little or nothing about. They transport us to imaginary worlds—unbelievable worlds—that lift us out of ourselves for a while or maybe a lifetime. They expand our understanding of differences among people, enlarge our knowledge about the world, and give us insight into our common humanity.
