The Reason for God by Timothy Keller is a highly recommended and accessible apologetic book. It's easy to read and great for a gift. (The accompanying DVD study is also a good investment.) There are also sermons that Keller has preached on the content of his books, in a series entitled The Trouble with Christianity: Why it's so Hard to Believe it. Those sermons can be found at Redeemer Presbyterian Church's website. Direct links to the audio files are below, or use the RSS Feed here.
