Everyday Grace by Marianne Williamson
Marianne Williamson believes the path to serenity lies in seeing every daily occurrence and issue as a spiritual one—and it doesn't have to be an arduous feat. Even with just 30 minutes, the most harried professional can find bliss. "I love this book," Oprah says. "It's about having hope, finding forgiveness and making miracles in your own lives. I think this is the best gift I could give you."
