Lee Strobel did write A Case for Christ, its about his 2 year search for the truth. He may have some atheist stuff out their but I doubt it. He's a devout Christian and a minister now. He does ask a lot of the questions that many people have about the reliability of the Bible and Jesus.
If you have questions like why does God let bad people live? or does God care? or Is God silent? or where is God today? Then I'd suggest Philip Yancey, especially Where is God When it Hurts and Disappointment with God. You can read some of his articles on www.christianitytoday.com
Just search out his name.
The Final Battle -- I don't think I've read that one. I did read one about a former Satanist who turned Christian and that was really scary because it shows how Satan works to attack us. Now I always ask God to surround me with angels to keep me safe from Satan's attacks.
Basically they were able to go out of body on purpose and attack your soul. There was one time when they went to attack someone and there were angles there to stop them.
It also talked about how easy it is to let demons into our souls and how many do it without even knowing it.
I wish I could remember the name of the book, something to do with a sword. I'll see if I can find the name, I'd love to read it again, it was oh my now I feel old, it was about 15 years ago that I read it, my junior year. The ironic thing is that my best friend and I had read it before we went to a fine arts symposium at simon fraser university. When everyone started the day with a chanting session we freaked out.
