Diary of An Activist is a social activism memoir journeying through vegetarianism, anti-nuclear and CND protests, feminist and queer activism, lesbian parties, coming out and becoming a parent. It features quirky Cork locations like the Quay Co-op and Loafer's Bar. It provides a unique insight into activism in Ireland in an era before mobile phones, computers and social media. It features gestetner machines, badge making machines and newspaper pages clipped to a clothes line. It includes both a trip to Greenham Common Women's Peace Camp and a trip on a pony over a mountain just to make a phone call in the local pub. Diary of an Activist is an intergenerational collaboration between activist and writer Orla Egan and artist Megan Luddy O'Leary. The beautifully illustrated story brings to light a history of activism that has previously been hidden, making it accessible and engaging.
