The Source: All going to Israel should read this. It's a long read and the first 1/3 is very dry but the rest is very good. It will give you an excellent perspective on how civilizations in Israel developed. I will buy lunch for the 1st person who figures out in Israel that we visit the book is about. :)
Acts Odyssey: This is a very good, easy read about Paul's journeys in Greece.
Where Jesus Prayed: I really like this summary of one woman's tour of Israel. She went on a "basic Bible tour" and we go to many more places but I love her commentary and how she related the sites to her faith journey.
We have multiple copies of The Source and Acts Odyssey to loan.
