Twenty years after the emergence of pesantren pop literature, novels were published written by kiai's daughters who were often called ning. The four novels, namely Hati Suhita, Dua Barista, Diary Ungu Rumaysha, and Cincin Kalabendu. Through these four novels, the lives of women in pesantren which have been closed for so long begin to emerge to the public. The nings explore themes of piety that reflect their unique experiences and perspectives as part of the pesantrenl's nuclear family. This research aims to show the narrative strategies used by writers in building piety discourse in pesantren literature. The sociology of literature approach and Saba Mahmood’s concept of religiosity are used to show the tension between traditions that tend to be patriarchal in pesantren and the demands of modernity. This research will contribute to the development of literary studies, especially pesantren literature, which has so far been dominated by male writers, as well as presenting the voices of pesantren women who have been "silenced".
