Their love is forbidden…and irresistible. The daughter of a half-Chinese duke and a lady fossil hunter, Lady Glory Cavendish is an idealistic and spirited miss who belongs to a secret society of lady investigators. Through her covert activities, Glory meets the handsome and mysterious Wei Chen, a master of healing and fighting arts. Fascinated by the noble shifu, Glory convinces him to take her on as a pupil. As they spend time together, however, she begins to long for lessons of a more intimate nature. Master Wei Chen has led a life of discipline focused on a single goal: avenging his murdered kin. His journey takes him to London where, by day, he treats opium users in his East End clinic and, by night, he secretly hunts the villain who destroyed his family. Yet for the first time, temptation distracts Wei: his spirited and lovely new pupil stirs dangerous needs in him. Desires that are forbidden between a shifu and his student…and between a commoner and a duke’s daughter. As Wei and Glory’s slow-burn romance ignites into fiery passion, they are drawn into a web of betrayal and deceit. Torn between honor and desire, revenge and love, the pair must decide if they will let the past determine their future…or if they will fight the shadows for their chance at happily ever after.
