This is a good book to read straight through, but it is scarier than the other books in the series.
Plot
The Coopers are called to the Middle East by the President of Nepur to investigate a large hole in the desert that is believed to be cursed. Of the many teams that have gone before them, none of them have achieved success. The hole is very strange (no one has come up with a natural explanation for it), there are venomous snakes in the area, and dangers from the general populace of the nearby city.
Morality
Dr. Cooper and Jay both resist the temptation to steal treasure; Jay says it belongs to the people of Nepur. Dr. Cooper cares for his family. All in all, the morality is good.
Spiritual Content
The Coopers' faith in God keeps them from following superstitions. The natives follow them to the area around the pit because they want to see them get killed by the supposed curse. A magician respects God and a man is saved.
Violence
A snake is shot and a man falls down a crevasse. Two people are kidnapped, but unharmed.
Drug and Alcohol Content
None.
Sexual Content
None.
Crude or Profane Language or Content
None.
Conclusion
This book has slight spiritual warfare; but it is not like his adult books. Everything in the book moves fairly fast and is exciting. Despite some scary elements, it's a clean, wholesome book for pre-teen kids who enjoy suspense and intrigue.
