Query: Horribly written.

First of all, this book is horribly written. A lot of it makes no sense; plus, the punctuation and grammar are disgraceful (if you need examples, just open the book to any page). This thing could not possibly have been copy-edited or proofread very closely--Sarah's last name is even spelled incorrectly on the spine! Second, the book is just a nasty unauthorized bio. The author engages in some ethically questionable methods to get her "information," and implies some outrageous things. Even if you're not a Sarah fan, you'll probably sympathize with her after reading this hatchet job. It must be tough having people write things like this about you. Please, please, don't waste your precious time and money on this debacle of a book.
