Lady Bai, called Wei-wei by her aristocratic family, has always been the perfectly obedient daughter--but only on the outside. When she dares to pay a forbidden visit to a public tea garden in men's clothing, only Gao looks close enough to notice her disguise.

When the pair witnesses a fatal stabbing, Wei-wei discovers that her brother has been hiding secrets. Street-smart with a shady past, the enigmatic Gao becomes her ally as she unravels the mystery, but soon she's faced with a cruel choice -- discover the truth and bring the killer to justice, or protect her family at all costs.
