'With but a few notable exceptions, scholarship on social movements reflects an outsider's perspective. But in this exceptional collection, the contributors take us inside global justice groups to describe and analyze the movements' unique brand of participatory democracy. The result is as rich an empirical portrait of the internal dynamics of a movement as has been produced to date.' Doug McAdam, Stanford University
