Goodreads: Off the blustery streets in the medieval heart of Budapest, Captain Tucker Wayne and his war dog, Kane, rescue a mysterious woman fleeing three armed men. The secret she holds will unlock a terrible treasure, one steeped in blood and treachery, tied to a crime going back to the fall of Nazi Germany and a heritage of suffering and pain that reaches out from the past to wreak havoc today. In a final showdown in the depths of a lost cemetery, truths will be unearthed, treasures exposed, and the fate of all will rest upon the shoulders of one man and a dog whose courage is beyond measure.
Interesting little novella but it did not make me want to start reading the Sigma Force series. I like James Rollins but this genre is not really my thing. Good story though.
