Interesting, but it is likely not what people expect.
The part about Frank Lucas, is only about a third of the book, the rest are devoted to essays the author wrote for various NYC magazines/newspapers.
The section on Frank Lucas is not a typical "true crime" written as long journalistic piece with lots of dates, places. Jacobson does give a background for what happened, but he is also attempting to convey more about Lucas' personality, overall it reads more like a feature piece.
The other pieces range from great to not great.
The author does have an ability/language to really give a feel for NYC street life, especially in the 1970s during, after the 60's/riots but before the yuppie 80's/Rent Era in Alphabet City/crack wars and way before Disney came to Times Square. The best stories are those that convey this time and/or the "other side" of the city, from the description fo 14th St. and 3rd Ave. before the Village became full of condos and pushed rents higher in this area bordering the Lower East Side; a stand-up club in Sheep's Head Bay; the rise and fall of a high end pimp; the last Irish Cowboy bank robber.
Other stories are a little weaker, the piece about 9/11 comes across as far left conispiracy screed, interviews with a firefighter and a widow keep from coming across as completely offensive, but it is also annoying because it is much more about national politics and not so much about NYC itself.
The piece about Winton Marsalis is great, if you enjoy jazz and are aware of the civil war within jazz between the "classicists" like Marsalis and the more modern, but if you do not know and do not care, it is kind of dull and again really does not convey much about NYC.
The piece about his family home and being a Yankee hater are good and give a sense of not only growing up in NYC but the generations have that come before.
Overall good, though be warned that Jacobson at times does suffer from the aging baby boomer disease--trying to convince us he is still hip while at the same time complaining how thing use to be.
