At the end of 2006, on a snowy night, Qin Zhang received a call from Chang Le, her sister who was not related to her by blood.
Chang Le timidly said, "Hello, Auntie. I'm Chang Le, Chang Jie's daughter. Could I please speak to him?"
Qin Zhang replied, "He can't come to the phone. He died last year."
Chang Le told her that her mother had passed away and that her stepfather had been kicking her bedroom door in the middle of the night.
Qin Zhang said, "All right. I'll have your second sister come pick you up."
And so Qin Zhang, the eldest sister and a top pharmaceutical sales rep; Chang Rui, the second sister and a beloved teacher; and Chang Le, the youngest sister and a high school student, came to live under the same roof.
At this point, Qin Zhang had six months left on her mission. She hoped to find the people who had killed her birth father, Qin Xian, and her adoptive father, Chang Jie; complete the mission they had carried on for two generations; and make sure Lele got into a good university.
A powerful, big-eating, big-drinking narcotics officer, Qin Zhang spends a heartwarming time in Linan with her two younger sisters, from winter to summer, from the deepest darkness to the break of dawn.
