I am such a sucker! My book collection has grown because of a few books I bought specifically due to these keywords.
A small list which could well be incomplete:
The Temple by Mathew Reilly
Cover of Temple
Peru. Inca. Idol. Guns. Pretty decent. Good read on a lonely day.
Seven Ancient Wonders by Mathew Reilly
Decent book. Lots of traps and thrills. Moments like the discovery of the Hanging Gardens are really good.
Six Sacred Stones by Mathew Reilly
Sequel to the above book. Same old stuff. The ending is a cliff hanger though.
The Last Testament by Sam Bourne
Cover of The Last Testament
Palestine. Israel. Biblical artifact. Middle east solution. Peace talks. Okay okay book. Not much of thrills to be frank.
The Rozabal Line by Ashwin Sanghi
This is book which jumps from one era to another in a short notice. This keeps things interesting but makes it hard to relate to the characters. Speaking of characters there are too many! It tackles the Jesus in India theory and very cleverly marries it to other religions. At times it may feel scholastic, but bored you certainly won't be! Highly recommended! The authors blog is here.
Drat! The list is smaller than I thought. Anyways, later days.
