This gussied-up little pamphlet is simultaneously two things: entirely correct, and utterly boring. The thesis is that democracy is best saved by bottom-up organizations and advisory bodies where citizens can gain practice in democracy, thereby empowering them and reducing feelings of learned helplessness and over-reliance on elites to solve problems. It's clearly true and recognizes that democracy is a muscle that requires constant exercise. But it's a truth that hovers very close to the surface of the obvious, so one expects a little new insight to justify publication.
Instead, the bulk of the book is handed over to examples of community organizing from Western Europe and the U.S., with very little theoretical scaffolding attached. The examples are fine, and occasionally inspiring, although they suffer from a couple defects: several were either failures or incomplete at the time of writing, and all of the case studies are written in a style reminiscent of bureaucratic whitepapers from bodies like the U.N. or the E.U. It's quite dull.
Further, the book never addresses the many, many difficulties facing contemporary democracies. There are a few mentions of populist bogeymen like Trump, but little recognition of the ways social media, partisan news, racism, sexism, classism, and the systematic immiseration of all but the 1% have conspired to weaken democratic action. This is more of a pep-talk than a serious engagement with the problems of modern governance. I have a lot of respect for the authors and they're definitely on the side of the angels. But this book is by no means a must-read.
