This book is an important addition to the literature on rebel group fragmentation. It offers a novel, nuanced argument and backs up its claims with a variety of tests. It also draws on new primary source material for the Irish Republican Army case study. This is essential reading for students, researchers, and practitioners studying why and how violent groups fragment. At times, Perkoski uses technical or specialized language that may be difficult for general readers to grasp.
