Rehtaeh Parsons was a gifted teenager with boundless curiosity and a love for family, science, and the natural world. But her life was derailed when she went to a friend's house for a sleepover and the two of them dropped by at a neighbour's house, where a group of boys were having a party.

The next day, one of the boys circulated a photo on social media: it showed Rehtaeh half naked, with a boy up against her. She had no recollection of what had happened. For 17 months, Rehtaeh was shamed from one school to the next. Bullied by her peers, she was scorned by their parents and her community. No charges were laid by the RCMP.

In comfortable, suburban Nova Scotia, Rehtaeh spiralled into depression. Failed by her school, the police, and the mental health system, Rehtaeh attempted suicide on April 4, 2013. She died three days later.

But her story didn't die with her. Rehtaeh's death shone a searing light on attitudes toward issues of consent and sexual assault. It also led to legislation on cyberbullying, a review of mental health services for teens, and an overhaul of how Canadian schools deal with cyber exploitation.

My Daughter Rehtaeh Parsons offers an unsparing look at Rehtaeh's story, the social forces that enable and perpetuate violence and misogyny among teenagers, and parental love in the midst of horrendous loss. (From Goose Lane Editions)
