Nadesan has read *all* of the literature on Foucault's concept of governmentality, and does a worthy job of organizing it into more-or-less coherent chunks on the workings of contemporary states and organizations. Biopower represents the means by which modern centers of authority organize subjects to maximize their vital forces, productive potential, and capacity for self-governance; the rationalities which define the only appropriate problem-solution spaces for the modern age. This book chronicles the mechanisms of biopower and the continual expansion of modes of surveillance and control.

That said, this is not a book for the beginning. Some familiarity with Foucault and biopower is highly recommended. It's also already a little dated, with too much of a focus on American politics of the period 2000-2008, particularly the neoconservative movement. There's a little too much slagging off everything bad in the world as the fault of neoliberal looter-capitalists. But for, say, a junior academic wondering how Foucault might be added to their work, this is a great resource.
