Having read almost all of the books about Jim Morrison, I must say that this is one of the most enjoyable books I have read on the subject.
While this book is filed in the 'Non-fiction' section, the author makes some interesting observations and puts forward some reasonable theories about what might have happened both leading up to and following Morrison's strange death. They're as plausible as anything Sugarman, Hopkins and Manzarek have written and perhaps more balanced!
Regardless of what your views are (and you might think this book is a work of complete fantasy) this is a must read for any Doors fan. Clooney knows his stuff about the band and writes in an honest style which is easy and enjoyable to read. If you're new to the Doors I would probably recommend you read John Densmore's Riders on the Storm first - but this is a great book with an unusual and refreshing approach to one of the most compelling mysteries in the history of rock 'n' roll.
