They spent three years researching the subject, and two more interviewing and photographing 90 craftswomen in 12 developing countries on 4 continents.

She began researching the book in 2006 while in Kenya working on Women Who Light the Dark, where she observed a “new international activist grandmother movement.”[9] Wonder Girls: Changing Our World, written with her granddaughter Alex Sangster, documents the work of groups of activist girls in thirteen different countries.

Musimbi Kanyoro, the president and CEO of the Global Fund for Women, wrote the foreword for the book.
