Under The Sky Of A Thousand Lanterns

Eighteen-year-old, Princess Su-ji finds herself the Empress of an unstable Empire when her father dies. Fiercely independent, Su-ji wishes to rule alone rather than wed but knows she must wed the Prince of the Qing Dynasty in order to sustain her reign.
But it is with Lee Seung-gi, Su-ji's fiercest rival for the throne, that the headstrong princess discovers the true meaning of love and desire.
