Hey, sure, the plot is simple (buncha tourists go to remote site, get kidnapped by radicals, some get killed, finally, well... don't want to spoil it....) Perhaps Conan Doyle has better work. But this is interesting for its content - the story could have taken place today. It's a great read because the reader will recognize that the Mideast hasn't really changed, that there's a timelessness, not just to the area, but to activities there. Different groups - the Assassins, the Dervishes, a Quaida, etc, have come and gone, but to what we currently call Radical Islam continues. Great read, partly for the characters, partly for the adventure, partly for the perspective.
While the Kindle edition advertises "live Table of Contents", it lacks live chapter heading links. You cannot use the Kindle 5-way control to jump among chapter headings. There's no excuse for this laziness in preparation. Lousy Kindle implementation.
