The Kingdom of Korin: Books 1- 2

The Prince of Korin
Prince Endomer of Korin is not a hero. Nor does he want to be one.
He spends his days in the royal library, poring over old manuscripts, studying archaic languages and playing chess. He's never been like Krollis, his fearless twin brother, who is an expert swordsman and hunts wild beasts in the forests.
When an army of vizzens, the fearsome old enemy of Korin, attacks from the east and Krollis disappears, Endomer is left in charge of the country. He struggles to find a way to save his people while his soldiers are dying and his citizens are forced to flee. As he fights to gain the respect of the palace court, he discovers a threat coming from within the palace walls. There is no one he can trust.
He isn't only fighting for his country – he's fighting for his life.

A Prince in Exile
The vizzen war is over but the palace is far from peaceful. Lord Gavindro, a foreign diplomat, arrives unexpectedly at the palace, his motives unclear. Endomer suspects something sinister lurks behind Lord Gavindro's supposed negotiations for trade, but Krollis refuses to listen to his concerns. When the contention between the two brothers escalates to the breaking point, Endomer leaves Korin and sails to Lord Gavindro's country to unearth the truth.
Across the sea, he discovers the threat goes far deeper than he imagined. A new enemy is on the rise, possessing weapons unlike anything seen before. Alone and far from home, Endomer is the only one who can stop the threat. To save his kingdom, he must face a dark villain determined to vanquish his people and all he's ever known.
