Seoul Shadows: Book 1 of the CIPHER SEOUL TRILOGY

With the help of Min-ho, a secretive new transfer student with uncanny skills, and her best friend Yuna, whose family restaurant hides underground connections, Ji-soo decodes her father's messages hidden in music. What she uncovers is devastating: her father was an intelligence agent who was murdered for discovering a vast conspiracy using K-pop choreography to transmit covert operational codes.

As Ji-soo infiltrates the glittering world of Korean entertainment to find proof, she becomes the target of Director Jung, the powerful intelligence chief behind her father's death. When Eclipse, Korea's hottest boy group, gets caught in the crossfire, Ji-soo must convince their leader that they're being used as unwitting pawns in a dangerous game.

Racing against time and pursued by deadly operatives, Ji-soo must navigate a web of deception where nothing is as it seems—not the entertainment industry, not the government she once trusted, and not even the quiet classmate who harbors his own vendetta against the conspiracy. With her father's encoded notebook as her guide, Ji-soo must expose the truth before she becomes the next victim of a conspiracy that moves to the rhythm of K-pop's perfectly synchronized choreography.

In a city where secrets pulse beneath the neon surface, the key to survival might just be hidden in plain sight—in the precise movements of a dance that millions watch but only few truly see.
