Heart Control Gu: 81 Days to Conquer an Empire

She has nothing—no lineage, no beauty, no power. Just a forbidden charm that can enslave even an emperor's heart. For 81 days, the mightiest ruler in the land becomes her puppet, and she transforms from a nameless southern maid into the true power behind the throne. Consorts, empresses, dowagers—they all bow before her invisible hand. But when the spell breaks, how will she survive the venomous intrigues of the harem she now controls? In a palace where one wrong move means death, she must turn temporary magic into permanent dominion before time runs out.
