The Nightblade Queen. The Vesmor Chronicles, #1

They say the Dusk Queen destroyed the world. They lied. A thousand years ago, the grief-stricken queen's magic shattered the land of Vesmor, severing the Dusklands from the remaining Five Kingdoms. Solnyr has spent every century since rewriting history - weaponizing the story, demonising her bloodline, and building an empire on a lie. Now, her heir rules the Dusklands: High Queen Zoryana Vekara, silver-eyed, iron-willed, and unwilling to kneel to the throne that blames her people for the sins of the past. When the Solnyrian King demands her surrender, he sends his brother - Prince Aurelian Solnyr, diplomat, idealist, and the last person prepared to question the truth of his own lineage. What begins as political negotiation becomes a collision of loyalty, desire, and the buried truth of what really caused the Breaking.
Because the real enemy isn't the Dusklands and her people - it is the history that was rewritten to keep them divided. And if the truth rises, so will the world.
