I have been anticipating this book for some time, and I was not disappointed. It provides in-depth write-ups on a number of the Bloodlines, along with new merits, combination disciplines, and other goodies. I personally enjoyed the Kiasyd and Samedi write ups the most, but I felt like they all brought something worthwhile to the table. For some it is largely a restatement and consolidation of things we've seen before, which is not necessarily a bad thing given the at times murky and contradictory backstories of some of the bloodlines, but for others it brings forth a number of new angles and possibilities to explore.
This is one of those books for which the descriptor should tell you whether or not you'll enjoy it. If you've read V20 and still aren't a big fan of the Bloodlines in general, while the writing, art, and greater insights might be enough to convert you, it's very possible there isn't much for you here. However, if the idea of this book sounds like something you would enjoy, then you will very likely be pleased.
This is a well-made book that delivers exactly what it promises, and it does it well. Probably my favorite v20 book so far, apart from the core.
