H. Rider Haggard 
Brethren 

Revered by fans as a master of the action-adventure genre, Henry Rider Haggard’s books are rip-roaring yarns in the classic sense of the term. Although many of his novels are set in far-flung locales, The Brethren is set in early medieval-era England. The plot hinges on a romantic rivalry between two brothers, with plenty of battlefield action thrown in for good measure.
