What more to write that others haven't? It's The Prince, Machiavelli's work, chances are you're coming in with a lot of preconceived notions, assumptions, or just intrigue.
First, the writing style. The book is divided into short essays. This makes it great for reading for 5 minute bursts or sitting down and reading at leisure. The language is natural and flowing, for the most part. Some of the references are to "contemporary" actions, which unless you study fifteenth-century Italian politics will be a bit over your head. Still, points are made, and examples usually at least have a sentence of background.
Now, the content. Not being in the business of power, I can't attest to the efficacy of the claims. The author certainly does a good job of making his case: using examples, hypotheticals, abstract theories and a dash of reason. I do now look at things like office politics, organized crime and international relations in a new light, trying to understand if the concepts still apply. Surprisingly, a number of them seem to play out no matter the stakes or timeframe. So for a new perspective, this book does deliver.
