Acclaimed writer Elif Shafak writes a letter to Jacinda Arden, Prime Minister of New Zealand after the Christchurch attack. Actress Yasmine AlMassri pens a poem about war for her mother. Activist and TV presenter June Sarpong addresses designer Diane Von Furstenberg.

These are a few of the moving and insightful letters that make up From Women to the World, a book which brings together letters from a global group of accomplished women - politicians, royalty, actors, writers, activists and more - every one addressed to a woman who means something to each of them. The results are extraordinary, heartfelt letters to historical figures, mentors, family members or inspiring ordinary people. Each is based on these women's personal histories and experiences, drawing attention to social issues such as homelessness, war, LGBT activism, mental health care or the plight of international refugees.

From Women to the World is more than a simple collection of letters - it is a book that shows a new model of leadership based on emotional intelligence and demonstrates how we have the wisdom to inspire, motivate and reinvent our world.
