As the middle of five kids growing up in dire poverty, the odds were low on Katriona O’Sullivan making anything of her life. When she became a mother at 15 and ended up homeless, what followed were five years of barely coping.

This is the extraordinary story – moving, funny, brave, and sometimes startling – of how Katriona turned her life around. How the seeds of self-belief planted by teachers in childhood stayed with her. How she found mentors whose encouragement revitalised those seeds in adulthood, leading her to become an award-winning academic whose work challenges barriers to education.
