Like young girls everywhere Katriona O’Sullivan grew up bright, enthusiastic, curious. But she was also surrounded by abject poverty and chaos, and after she became pregnant and homeless at 15, what followed was five years of barely surviving.

Yet today Katriona is an award-winning academic whose work explores barriers to education for girls like her. What set Katriona on this unexpected path were the mentors and supporters who truly saw her. The teachers who showed her how to wash in the school toilets or turned up at her door to convince her to sit at least one GCSE.

The community worker who encouraged her to apply for training schemes. The friend who introduced Katriona to Trinity College’s access program while she was a cleaner. Simple acts that would help her turn her life around.

Told with warmth, clarity and compassion – compassion for her parents, for her younger self, for others – Poor is both an astonishing personal testimony and an impassioned plea for the future of our children.
