What Book Has Changed Your Life?

I've spent the last couple of days deciding what books I want to read in 2016. This was sparked by The 2016 Reading Challenge on Tim Challies' blog this week. I printed off the challenge, taped it in my bullet journal, and started marking it up with the titles I would like to read.

My husband and I have an embarrassing number of books on our shelves that we have not read yet. We have always been readers, but have slowed down quite a bit (with the adult reading, anyway) since having children. Somehow our book acquisition rate has not slowed with our reading rate. The truth is, we still want to be avid readers, and are not willing to let that image of ourselves go. We need a plan.

Given our shelves full of books, I populated most of the list with titles from our bookshelves. Books we don't own will hopefully come from the local library.

Here are some of my picks so far:
A book about Christian living: The Imitation of Christ by Thomas a Kempis (on my shelf)
A biography: The Personal Life of David Livingstone by William Blaikie (on my shelf)
A classic novel: A Tale of Two Cities by Charles Dickens (already started, will finish in 2016)
A commentary on a book of the Bible: I Wish Someone Would Explain Hebrews to Me by Stuart Olyott (on my shelf)
A book with the word "gospel" in the title or subtitle: The Explicit Gospel by Matt Chandler (on my shelf)
A book more than 100 years old: Kept for the Master's Use by Frances Havergal (on my shelf)
A mystery or detective novel: Arthur & George by Julian Barnes (at my library) or something by Dorothy Sayers (also at my library)
A book with at least 400 pages: George Whitefield Vol. 1 by Arnold Dallimore (on my shelf)
A graphic novel: Batman: The Dark Knight Returns by Frank Miller (at my library)

One recommendation stopped me, though. "A book someone tells you 'changed my life.'" So I decided to turn to you, dear readers. What book has changed your life?

I can't exactly return the favour, because I don't really tend to think in dramatic terms like that. Usually if a book has come close to "changing my life" it's because it was at the culmination of a long process of life or thought change anyway. Other books have changed my life for a few years or a decade, but the change has not been permanent. But I will give you a list of a few of the best books of my life, if you like.
