The White Rose (Merilithien Saga book 1)

For years, the kingdom of Eyther has slowly spiraled into decay. Corruption is rampant in the High Courts, and the king's isolationist policies have damaged valuable trade relations with the human cities to the south. Rhenduin Mahruna, brother of the king, has long foreseen his beloved nation's fall, and has fought to maintain the peace and prosperity of centuries past.
But when a mysterious, young girl arrives at the kingdom on the brink of death, and a past scandal of the royal family rises from its ashes, everything Rhenduin has fought for comes crashing to the ground. A hostile empire is rising in the north, and old enemies have their sights set revenge.
Rhenduin, his son, and the young girl are thrown into the midst of a growing chaos. War might just be inevitable.
And the girl may be the sole key to victory.
