The bandit queens by Parini Shroff

For Geeta, life as a widow is more peaceful than life as a wife. Until the other women in her village decide they want to be widows, too. Geeta is believed to have killed her vanished husband - a rumour she hasn't bothered trying to correct, because a reputation like that can keep a single woman safe in rural India. But when she's approached for help in ridding another wife of her abusive drunk of a husband, her reluctant agreement sets in motion a chain of events that will change the lives of all the women in the village.
