Boy of Stone by Andrew Oakes

A small village stripped of its male children, fired and ploughed beneath the earth, its name erased from all maps... this is the bloody starting point that triggers the involvement of Sun Piao, Senior Investigator with the Homicide Squad of the Shanghai Public Security Bureau. The deeper that he digs, the greater the political involvement and the corruption. Against all odds he battles with an investigation whose roots go back to the violent era of the Cultural Revolution, and which threaten the new China with such.
