What is life like for aid workers who gather from around the world to serve refugees who have fled their homes due to famine, political unrest, and disasters?Kiwi nurse-midwife, Barbara Walker – who spent 20 years working for international aid agencies – shares her dramatic, heart-rending, and inspiring stories of the situations she faced and the people she sought to help.From the Sakeo One Refugee Camp in Thailand, where she cared for those fleeing Pol Pot’s regime in Cambodia in a make-shift bamboo-framed field hospital, to her last placement in Mozambique that ended due to a death threat, Barbara’s Christian faith gave her strength and kept her focussed.We also learn of Barbara’s early life in New Zealand, and her later call to ordained ministry as a chaplain when she returned after serving overseas.Barbara hopes that her story will inspire and encourage all who read it to think outside the square and seek to make a difference in the world in which we all live.Post COVID-19, we all have a chance to move forward, working together to address the inequalities which she has seen around the world and here in her country of Aotearoa New Zealand. We cannot make changes alone, but by listening, sharing, building trust, and working in partnership, we can make a difference for all. It’s up to us all.Praise for Purple Hands:“You are in for a riveting read. Expect to laugh a lot and maybe cry a bit.
