Lu Qingyan, the daughter of a Jiangnan tea merchant, is as radiant as the April sun, yet harbors a secret: she is the last surviving descendant of the previous dynasty. When a lost imperial jade pendant draws her into a storm of intrigue, Crown Prince Gu Changyuan meets her eyes, which seem strangely familiar. The gentle, jade-like heir to the throne begins to doubt the order he has believed in for over a decade.
In the shadows, Grand Secretary Shen Moyan has been laying his pieces for twenty years. Beneath his refined facade lies a lie powerful enough to bring down the dynasty. In the open, the general's adopted daughter Su Mingyue stands with her bow drawn, while resentment and jealousy simmer beneath their sisterly bond. And in the trembling hands of old wet nurse Nanny Zhao lies a secret document bearing an identity that could burn everything to the ground.
Lu Qinghan weaves a web with her smiles, searching for the truth between the fragrance of tea and palace banquets. When four people's fates become entangled in the same conspiracy, she will uncover with her own hands the mystery of her birth, concealed for seventeen years.
