Therese Vanier, founder of L'Arche in the UK, was also a distinguished doctor who worked with Cecily Saunders at the world-renowned St Christopher's Hospice in London, and a tireless contributor to Christian ecumenism and interfaith understanding. This biography draws on the memories of nearly fifty people who knew her, as well as her own published and unpublished writings, to offer a tribute to Therese and a critical assessment of her lasting legacy in the three areas of her work. Includes photo section.
