Bound by Blood The Dragon King's Bargain

To save millions, a father had to become a sovereign.
The bargain was struck in a cavern of obsidian and molten gold, sealed not with ink, but with an ancient, binding vow. The human king would submit his greatest treasure to the heavens to ensure the safety of his borders. He gave his word, promising his eldest daughter, Rajkumari Avani, to the absolute ruler of the skies. She was to be the blood sacrifice disguised as a bride-a fragile, mortal token handed directly to the terrifying, unyielding Black Gold Dragon King, Devendra.
Avani was born of the earth, destined to be crushed under the weight of a draconic crown.
Yet, destiny is a fickle poet. It loves a tragedy, but it delights in chaos. For as the celestial wheels began to turn and the summoning rituals were prepared in the hidden temples of the palace, a cosmic tear was forming-not looking toward the grand history of the kingdoms, but reaching out into a completely different century, targeting a small, cluttered bedroom where a completely different girl was about to change the fate of the empire forever.
