For more than twenty-five years, David Nott has taken unpaid leave from his job as a general and vascular surgeon with the NHS to volunteer in some of the world’s most dangerous war zones.

When her husband died, leaving her alone with two small daughters to raise, she threw herself wholeheartedly into ‘adventure medicine’, seeking out the world’s most remote corners – on land and at sea – to practise her healing, both her own and others.

Working in wild places from the Kruger Park to the Australian Outback, the Atlantic Ocean islands, and both the south and north poles, ‘Doctor Joan’ dealt with a vast range of medical issues, from rabies to deep-vein thrombosis, childbirth to wisdom-tooth extraction, catatonia to depression.

Showing an eagerness to learn and a humility that isn’t always a given in her profession, and with a wry eye and a sympathetic outlook, Joan Louwrens has written a memoir that’s a poignant and often funny story of a life lived to the full
