Hungry - Pre-Order Now
Hungry is the powerful new memoir from Number One bestselling author Katriona O'Sullivan - a raw, courageous exploration of survival, identity and the lifelong search for self-acceptance.
Raised in a home marked by poverty, addiction and abuse, Katriona defied the odds: from teenage motherhood struggling with her own addictions to becoming a university professor and successful author. But beneath the achievements lay a more private struggle - with her body, her worth, and the unrelenting drive to be enough.
In this fiercely honest memoir, she interrogates how trauma, class and gender shape the way women see themselves - and how society teaches them to measure their value.
Told with stunning courage and vulnerability, Hungry is both a personal reckoning and a powerful reclaiming of body, voice and self. It is one woman's story - and a rallying cry for every woman who has ever felt she had to shrink to survive.
