'This is an indispensable guide for those considering volunteering in global mental health but should also be read by global health practitioners - it provides a practical road map as well as a thoughtful consideration of ethical issues and how to navigate different sociocultural, economic and political contexts. The reflections from volunteers who have worked across very diverse settings injects authenticity and brings home the challenges, opportunities and rewards of taking an alternative path- I will keep coming back to this.' Rashida A. Ferrand, Professor of International Health, London School of Hygiene and Tropical Medicine, UK; Director of The Health Research Unit Zimbabwe, Biomedical Research and Training Institute, Zimbabwe 'This is a hugely welcome collection on volunteering in mental health for underserved populations. It covers critical ethical principles, and provides practical tips. It will be useful for those contemplating volunteering, or about to begin, and also for people with additional experience. I particularly valued the emphasis on learning from partners and on sustainability, and the framing of volunteering as part of building equitable long-term partnerships,. The book importantly alludes to planning for ongoing mentoring of colleagues in the host setting after the volunteer is back in their usual workplace. Volunteering in global mental health is likely to be a hugely rewarding life-changing experience and this book will inspire many to take the next step.'
