Favorite Book Ever

What is your favorite book? Singular. Not a list. What is the very best book you have ever read? And why is it your fave?

The novel that shook my world is a combination of satire on human depravity, meditation on faith, murder mystery, love story (or two), legal thriller, testament to courage, and ultimately an apologetic for grace, grace, grace: Dostoyevsky's Brothers Karamazov. One of the numerous Amazon reviewers who commented on this classic said, basically, "I'm an agnostic, but almost doth Dostoevsky persuade me to become a Christian." This book convinced me it was possible to tell a story in such a way that people would fall in love with grace. And it could be pulled off without including one sermon, altar call, sinner's prayer, "Four Spiritual Laws," or iota of Christianese.
