House of War and Bone

Esther Kalina Anheime, heir to the throne of the once bustling country of Valeborne, is in dire danger. War has come to her Kingdom's doorstep, and the world as she knows it has been ripped apart. Her mother has been assasinated, her father rests in grief and the Kingdom rages at its loss. As Nyavian forces close in on her father's fortress, he must ready for war and prepare to preserve her life at all costs, no matter how steep.
Up the Nyavi river and high into the mountains bordering the North of Valeborne, lies a kingdom untouched by threat. Its King is but a boy. A boy with monster blood in his veins and tinsel eyes. High in these mountains lies the Castle Lyrne, a towering behemoth of a fortress made of jet black Marble and hewn brick, a hankering sight to behold. Voices with no body echo in the corridors, screams rise up from the dungeon, maimed soldiers guard the doors, and creatures like no other roam the halls. So fearsome is its young warrior king that no kingdom dare stand against it. The subjects scream at the mention of the king's name, and his enemies have never lived to tell their tales.
Kershtan Hollen has been King since he was but fourteen years of age, his entire family torn from him by a traitorous poisoning that did not succeed in killing him. Bitter, angry, and truly monstrous inside, he is the safest harbor for Esther.
With the agreement set, Esther is to spend her exile inside the walls of Castle Lyrne, where monsters haunt her waking hours and Kershtan makes it clear she is little away from his prisoner.
Slowly, like the grains of sand in a timeglass, Kershtan falls in love.
Night collides with Day.
Esther has become his salvation, and he will stop at nothing to protect her life.
Even if it means plunging into war.
