Query: This is a good book, not a great book

I am not the author and I don't really believe Judith Fitzgerald has either the time or the inclination to hang around writing reviews of her own book. I read the book. It's good and it's entertaining. It's not the best unauthorized bio I've read (ie there's no talk about drugs or sex or rock and roll per say) but, all the more reason to read it, as far as I'm concerned.
