Keren Weitzberg (Institute of Advanced Studies, University College London) on her new book We Do Not Have Borders: Greater Somalia and the Predicaments of Belonging in Kenya. She grapples with the long history of Somali migration across colonial/post-colonial borders, definitions of "Somaliness," media coverage and representations of Somali people, and the "hidden history" of women gleaned from poetry and interviews.
