Garrett Felber’s powerful biography, A Continuous Struggle: The Revolutionary Life of Martin Sostre, excavates his many contributions as well as the work of his support committee in the successful Free Martin Sostre movement. This week, Kite Line spoke with Garrett about his work on Sostre and its connections to the struggles continuing to our present day.
