This book is very much a cut-and-paste job with information gleaned from previous biographies and interviews and no new material save for the author's own opinions, which are occasionally very misinformed. It's one thing to have your own opinion, but very early on Jackson makes some really basic errors about the 1970s music scene and forms opinions based on those errors. Some of her descriptions of people in Diamond's life are obviously based on photographs and nothing else, and these descriptions are used to flesh out the word count. Overuse of glowing descriptors like "intriguing" or "enthusiastic" pad out the content, as do cliches like "knuckle down" or "talking out of school."
Also, Jackson full-on lies about certain events in Neil Diamond's life to cover problematic areas. These events are things that Neil himself has talked about, rarely of course, but they are easy to find either scanned online or in cheap back issues from the 70s (People, Rolling Stone, Stars and Stripes, Newsweek, etc.) The last real biographies on Neil were done in 1987, and the material in Jackson's book from 1987 on is notably sketchier and less comprehensive than what's written about 1987 and before, which tells you exactly where Jackson got all her info.
Further, given that this author has somehow managed to write 15 in-depth biographies over the past 17 years -- releasing some of them with multiple titles as though they were new books -- makes me wonder just what is going on here.
If you want to learn about Neil Diamond, don't start here. What you need to do is first realize that he has not been officially involved (nor unofficially, as far as I know, except perhaps with David Wild's semi-bio) with any book. You should also know that the information he has given in interviews is often contradictory. Accept this, learn to live with it, then go read He Is...I Say by David Wild if you want a nice overview of Neil's life. The liner notes for the In My Lifetime music set are also very informative. If you want more detail, try Solitary Star by Rich Wiseman and Diamond: A Biography by Grossman et al. Solitary Star is seen as more negative by the fans, and while the author does seem to be very irritated with Diamond throughout the book, he includes interviews from people who really like Neil so it's not all negative. Diamond: A Biography is more positive, sometimes so much so that they fudge the facts or completely avoid problematic areas. (For example, Solitary Star goes into a lot of detail about the lawsuit and Lee Holdridge credit fiasco for Jonathan Livingston Seagull, while Diamond: A Biography skims over it.) Both Solitary Star and Diamond have errors, but Solitary Star's errors are entirely on the part of the people who were interviewed. Diamond: A Biography has errors that seem deliberate. Also, note both were written in 1987 so they have no real new material. If you're looking for dirt, you're probably out of luck. None of the books out there go much into groupies or drugs or affairs, and most avoid discussing Neil's kids, which I personally think is only fair since Diamond himself did not contribute to any books. But you might as well buy Solitary Star and Diamond: A Biography and get the relatively original information rather than read it in Jackson's bland book.
