Clay and the River of Silver: The Alexander Clay Series, Book 11 (Unabridged‪)‬

In the aftermath of the Battle of Trafalgar, the Royal Navy are taking the war to the enemy. Captain Alexander Clay and the crew of the Griffin are chosen as part of a major expedition to the South Atlantic. They are tasked with taking back control of the Cape, but find that they are drawn into a stranger conflict. 

Across the ocean, South America is on the brink of revolution. Clay must not only fight the French, but also navigate his way through the murky waters of the Rio de la Plata. 

Here, Freedom Fighters hungry for power, American gunrunners, and the ambitions of his own commander make for an explosive mixture. And running through it all is the River of Silver.
