I have read or listened to probably 40 + of the EU books, and even the worst of those was far better than this. It was an erratic, sloppy mess. One of the things that I hated the most was that the author could not decide whether he was writing Star Wars, or earth (most of the references to animals in this book are earth animals, not some fantasy animal existing in the Star Wars vocabulary or new ones to describe). I know it seems small, but that is one of the many thing that were done very poorly in this book.
It will not run this Star Wars fan off (yet), but they are going to have to up their game if they want to be as good as what star wars fans are used to.
