Someone she trained with is killing their own people. And Yue Lin is next on the list.

Grace Chen was the smartest person in their SDU intake. Now she's a military contractor using corrupted bazi techniques to eliminate anyone who might expose her. Three former operatives are dead. Yue Lin's birth chart is in Grace's tablet — flagged, marked, one press of a button away from a death date she can't fight alone.

Wang can counter the technique. But Grace doesn't fight like the enemies they've faced before. She doesn't want power or proof. She wants survival — and she's willing to kill everyone Yue Lin loves to get it.

When the office burns and everything they've built turns to ash, Wang and Yue Lin face the hardest truth of their lives: you can rebuild walls. You can rebuild a school. But you can't rebuild trust — and Grace was once family.

The explosive finale of the KOWLOON NIGHTS series. Fire. Rebirth. And a love that refuses to die.
