Books that Change Lives

I have found that there are certain books that really do change your life. These type of books come along every so often and are totally unique to each individual person. Some of them may be classics; the type of books that are acknowleged as standards in their particular genre. Others may be more obscure, holding a special meaning for the reader. Regardless of how well a book of this kind is known, they all have one thing in common. They cause the reader to look at the world in a totally different way then he or she did before they cracked open the pages. This kind of book is read at a time in the readers life when the message that it conveys is needed. It may not appear to be a life-altering message, but it communicates to the reader exactly what they need to hear at that time. These books change us, imparting some type of wisdom or understanding of the world that we would never be the same without. They shape our thinking in such a way that we can point to them as turning points in our lives. In thinking about this concept of the "life-changing book," I have thought of a few books that fit this description for myself:

Chosen By God - R.C. Sproul
Orthodoxy - G.K. Chesterton
On Christian Liberty - Martin Luther
God Will Bless You - Charles Spurgeon
Confessions - St. Augustine
The Screwtape Letters - C.S. Lewis
The Memoirs of Sherlock Holmes - Sir Arthur Conan Doyle
The Dark is Rising - Susan Cooper
Chronicles, Vol. 1 - Bob Dylan

Please feel free to leave a comment with a title or two (or a list if you like) that might fit the description for you.
