Book excerpt: The extraordinary humanitarian Samantha Nutt gives a bracing and uncompromising account of her work in some of the most devastated corners of the world - and a new, provocative vision for changing course on growing militarisation. It is a brilliant distillation of Dr Nutt's observations over the course of 15 years providing hands-on care in some of the world's most violent flashpoints. Combining original research with her personal story, it is a deeply thoughtful meditation on war as it is being waged around the world against millions of civilians.
