As an overall product I would say this gets a 3/5.
Immediately we lose a point as we come to one of Catalyst's long standing problems with 5e, a lack of proofreading in the crunch section of this book. At release a table to calculate social rolls and their interactions with various cons was completely missing. More alarming, it seems like the writers have in some places bare-faced copy pasted some rules and equipment from previous editions without updating them to 5e. An index is not to be had either, which in a book detailing Constantinople and its many intricacies can be a pain in the butt when you need to remember the name of that bar. This is simpler to address in the pdf version, but for print, its simply inexcusable.
The fluff of this book is generally well written, detailing who what and when things are going to be happening in the Seattle surprise election, as well as detailing a number of different types of cons that players can perform in order to achieve a social approach to an issue. Additionally there is a very in-depth look at corporate politics in Europe, as well as another tease at who might become the new 10th AAA company. Constantinople is lovely city in real life, and I hope I can leverage some of the information there for future games.
Another issue I have to take here however is the lack of seperation between player knowledge and game master knowledge. One of the most frustrating parts of the whole CCD craze has been the lack of information I as a GM have in running it, especially during the beginning of the plot line. Once again Catalyst blankly states up front who and what the candidates are (or are not) to both player and GM. In a game about corporate secrets and deniable assets you would think that the authors would know how to keep information seperate by now.
