Book Review: Fully Human as a non-binary concept is no particularly innovative proposal, given that other scholars have developed similar ideas of degrees of citizenship. 27 Moreover, one could criticise that other (non-ethnically defined) groups could have been added to the discussion — for example, along the lines of disability, gender and sexual orientation, or conduct (as in the case of convicted criminals losing their right to vote as a consequence of a prison sentence, or alleged terrorists being deprived of citizenship). Nevertheless, with its focus on stateless persons; forcibly displaced persons; irregular migrants; nomadic peoples; indigenous nations; and secondclass citizens, Kingston’s book offers a convincing analysis of the problem, an interesting normative claim and very practical first steps towards possible solutions. Kingston thereby makes a valuable and important contribution to the emerging field of statelessness studies. It will not only be interesting for academics in the fields of law, political theory, international relations, sociology, anthropology or history but also for practitioners — activists, journalists, lawyers, or migration authorities — and, maybe most importantly, for individuals claiming full and functioning citizenship. 27 One might think of Elizabeth F Cohen, Margaret Somers or Iris Marion Young on whose work Kingston draws in her book, but also scholars such as Linda Bosniak, Audrey Macklin, Nira Yuval Davies or Leti Volpp. 194
