A must read for anyone even remotely interested in Colombia. It is admittedly a tough read at times (it was the first time I had encountered the term "parastate," for example), and as some other reviewers have pointed out, it almost reads as a Ph.D dissertation rather than as a book.
Forrest Hylton is the real deal though. I spoke to a Colombian historian about him who was surprised at the level of research a non-Colombian would put up with in order to write this, and he's right. Hylton goes into an enormous amount of detail in this book, and as a soon-to-be-nationalized Colombian, I can say that the bits on Alvaro Uribe were essential reading whether or not the reader is Uribista. The history of Colombian paramilitaries is often overlooked since FARC hogs up all the headlines. This book changes that.
If you are Colombian or are interested in Colombia's changing socio-political climate, read this book.
