The Noble Mercenary — Patrick John Donahoe

The Noble Mercenary is the second book in The Fellowship of the Ancient Covenant series. Our four heroes' genesis story continues in Jerusalem, Constantinople, France, and Ireland, as they attempt to thwart the machinations of thieves, pirates, and an ruthless clan chieftain. In the modern day stories, the four must prevent an assassination attempt on a head of state, and a drone attack on South Korea, orchestrated by billionaire terrorists, who belong to a secret organization called the Select.
