A great book, while Morgan is a really dense writer, I think anything she writes is worth the extra effort to take in on all levels.
I read this for a graduate course, so I've included a shorter version of my overall assessment of the book. I’m not sure that there’s a clear balance between the consumptive nature of the European economy, the African economy from which the enslaved peoples came, and the African captives’ navigation between the two. There’s little explanation for the systems of value and trade that predated the European system in Africa; and while that could be due to a lack of precise scholarship, Morgan does not entirely acknowledge the fact in that case. All of these, however, point towards a conclusion about the more technical aspects of the book as a whole, which is that she tends to write towards an audience that is intimately familiar with the history and surrounding scholarship of the early Black Atlantic. This point is further highlighted by the lack of geographic specificity. While all of the areas she includes occupy the same general space of West Africa, there is enough geographical distance between them that warrants either some explanation or acknowledgement of the confirmed, potential, or possibly lack-of scholarly of the diverse and/or cohesive dynamics of culture, trade, and value that existed across the more-than 2,000 mile span of the geographical area at play.
This all being said, though, it is truly admirable just how much content this book spans. Jennifer Morgan is certainly an author who I always encourage people to read, and one of the best in modern historical scholarship.
