I can remember one, it was called "Who Moved the Stone" by Frank Morrison - there is a very recent update 2017.
Who Moved The Stone: 2017 Edition (Christian Classics)
by Frank Morison and Charles Eastwood $3.57 for Kindle.
The 1st edition came out in 1930 and the English was very old fashioned, hope this edition is better.
Another one of the books was "Evidence That Demands a Verdict" by Josh McDowell, this has also been updated.
You can get it in many formats, I would recommend the latest (1999) and also get this in hardback rather than Kindle - it's a huge book with tons of information.
The New Evidence That Demands A Verdict: Evidence I & II Fully Updated in One Volume To Answer The Questions Challenging Christians in the 21st Century. Hardcover – November 23, 1999
by Josh McDowell (Author)4.7 out of 5 stars 591 ratings See all formats and editions
There were many other books but I remember those best.
I would also check out any books by Lee Strobel.
