The Moses Expedition by Juan Gomez-Jurado is a real thriller. Once you start this book, try putting it down for more than a few moments before you are back to reading more. I just finished it today and passed up a bike ride in the process.
The search for the Ark of the Covenant and the original stone tablets of the Ten Commandments is the basis of the plot, but the other components of the plot and how the author ties them all together is what makes this book so darn good. Rather than go on about this book let me share the synopsis found on the inside cover of the book jacket with you.
"After fifty years in hiding, the Nazi war criminal known as the Butcher of Spielgelgrund has finally been tracked down by Father Anthony Fowler, a CIA operative and a member of the Vatican's secret service. He wants something from the Butcher--a candle covered in filigree gold that was stolen from a Jewish family many years before. But it isn't the gold Fowler is after. As Fowler holds a flame to the wax, the missing fragment of an ancient map that uncovers the location of the Ten Commandments given to Moses is revealed. Soon Fowler is involved in an expedition to Jordan set up by a reclusive billionaire. But there is a traitor in the group who has ties to terrorist organizations back in the United States, and who is patiently awaiting the moment to strike. From wartime Vienna to terrorist cells in New York and a lost valley in Jordan, The Moses Expedition is a thrilling read about a quest for power and the secrets of an ancient world."
If that doesn't convince you to read this book, then just take my word for it. This is a great read.
