What are the 10 books that have had the biggest impact on your life?

A recent Internet meme asked, "What are the 10 books that have had the biggest impact on your life?" These aren't necessarily your favorite books, although some titles are bound to overlap. But what books have changed your life, or made passages and themes stick to your mind like wet biscuit dough long after they're put down? What made you realize a hidden truth or look at the world in a slightly--or majorly--different way? As an addicted reader, it's hard to narrow it down to just 10. But here goes:

- The Bible

- Tarzan of the Apes by Edgar Rice Burroughs

- Gates of Fire by Stephen Pressfield

- On a Clear Day You Can See General Motors by John DeLorean

- The Seven Levels of Intimacy by Matthew Kelly

- The Shack by William P. Young

- The Case for Christ by Lee Strobel

- Lord of the Rings by J.R.R. Tolkien

- The Chronicles of Thomas Covenant by Stephen R. Donaldson

- Origins of Marvel Comics by Stan Lee

What are some of your choices?
