Husband-and-wife team Sam and Remi Fargo are intrigued when an archaeologist friend requests their help excavating a top secret historical site.  What they find will set them on a hunt for a prize greater than they could ever imagine.   The clues point to the hidden tomb of Attila the Hun, the High King who was reportedly buried with a vast fortune of gold and jewels and plunder... a bounty that has never been found.   As they follow the trail through Hungary, Italy, France, Russia, and Kazakhstan — a trail that they discover leads them not to one tomb, but five — the Fargos will find themselves pitted against a thieving group of amateur treasure hunters, a cunning Russian businessman, and a ruthless Hungarian who claims direct descent from Attila himself... and will stop at nothing to claim the tombs’ riches as his own.
