King's Shield

Acclaimed Inda series within Sherwood Smith's epic fantasy Sartorias-deles universe . Military fantasy woven with courtly politics, vast worldbuilding, and diverse charactersInda was the second son of the prince and princess of Choraed Elgaer. It had been Inda's fate, as second son, to be his family's Shield Arm and spend his adult life protecting the lands his brother would one day inherit. But powerful factions in the royal court were committed to seeing Inda fail.
For eight difficult years, Inda had been at sea, using an assumed name and forcing himself to never think of all he had lost. And he had created a new life, for the military skills that had been trained into him and his own inborn leadership ability could not be erased. After founding a mercenary marine company, he had earned a reputation for defeating dangerous pirate fleets. When Inda discovers that his home country is about to be attacked from the sea by an ancient enemy, he throws his carefully guarded anonymity to the winds and returns home.
After nearly a decade at sea, Inda finds his home utterly changed. His good friend Evred, the formerly powerless and harassed younger prince, is now king. Evred has heard of Inda's martial accomplishments at sea, and is determined to make Inda his Royal Shield Arm-the person in charge of defending the entire kingdom. Though Inda is skilled, his experience is entirely naval. Can a former pirate captain alter his tactics to become a successful ground commander in time to save his endangered homeland?
