Jang Tae Yoo

Early in his reign, King Se Jong accidentally causes the death of his in-laws and their slaves in an attempt to save them from his brutal father, King Tae Jong. Two young slaves, Ddol Bok and his friend Dam, survive, but neither knows the other has. Ddol Bok blames the king and vows to kill him to avenge the deaths of everyone he loves. He spends several years becoming a great warrior. Dam, who has a photographic memory, becomes a court lady called So I, but she feels so guilty about her role in the other slaves' deaths that she is mute. Ddol Bok returns to the palace under the name of Kang Chae Yun in order to kill the king. However, he becomes embroiled in the mystery surrounding the deaths of several Hall of Worthies scholars. The deaths were caused by a secret society called "Hidden Root", which was created long ago by followers of Jung Do Jeon, with the goal of giving more power to ministers and less to the king. King Tae Jong killed Jung Do Jeon and all of his family except his nephew, Jung Gi Jun, who is now the leader of Hidden Root and lives in disguise not far from King Se Jong.

Set in a dazzling blend of past and present, the story follows Chef Yeon Ji Yeong, a perfectionist French-trained chef at the peak of her culinary career, who is suddenly transported back in time to the royal palace. There, she’s forced to cook for an infamously temperamental tyrant, King Yi Heon, a ruler with a killer palate and a deadly temper. Yeon Ji Yeong is a modern woman caught in a cutthroat world of palace politics, survival cooking, and unexpected romance. Her mission? Survive the royal kitchen, win over the impossible King, and maybe, just maybe, rewrite the future. King Yi Heon is a ruler whose sharp mind and sharper tongue make him both feared and misunderstood. With an unparalleled sense of taste and zero tolerance for mediocrity, his court lives in fear of his next meal. But when a fiery new chef enters his palace, the king’s taste buds – and perhaps his heart — begin to change.
