That should give you an idea of the range of this book. Okrent leaves no rock unturned in this detailed history of the Prohibition era. The book starts with the political manueverings and personalities that got the 18th amendment passed. All fascinating. It moves on to describe the legal, political, judicial, economic and social impacts of Prohibition's enactment and enforcement, not just in the United States but in Canada, the Caribbean and Europe. Finally it tackles the rather fast fall from favor and repeal of Prohibition and closes with a short reflection on how the movers and shakers of the time have been essentially erased from our cultural memory.
In individual paragraphs and sections, the book is great. The stories are carefully researched and detailed and the individuals and events are really interesting. When taken in portions of more than a couple of pages however, it's just dense. Especially the first half where the movement is kind of gelling from different sections of society. There's no overarching narrative, so it's hard to stay engaged. I ended up reading it in 15 minute stints on my lunch break (thus, it took 4 months to finish). The actual Prohibition-era sections were much more fun, a lot of Baptists & Bootleggers type stuff.
Fans of history will enjoy this book, especially those that are amazed by the power of lobbyists (hint: Prohibitionists invented modern lobbying). It may be dense, but the individual stories are fascinating and often amusing. I recommend the book and intend to check out the PBS miniseries that is it's companion.
