I've read several Plath biographies, along with her journals, letters home, and her collected works. If you wants to feel like you have a real sense of Plath's character, you should read her unabridged journals. And if you want a peek into the end of her life, you should be reading the Ariel poems, as Hughes burned her last journals and her book that chronicled his betrayal. That being said, this is probably the best biography of hers that I've read, mostly because it is free of the mauling by the bloody paws of Olwyn Hughes, Ted Hughe's sister. It's common knowledge that Olwyn hated Plath (she says as much to the public), but what's worse is that she used Plath's biographers to consistently tell a warped version of the story in order to exonerate Hughes' blame, consistently making Plath seem difficult and insufferable. (This is even more annoying when you consider that most of Olwyn's wealth comes from royalties from the Plath estate). Anyway, this biography does a great job because it's able to duck Olwyn's edits and still have permission to use Plath's work along with Hughe's letters. The biography interviews people who saw her at the end of her life as panicked, unhinged, and difficult, but it also interviews people who loved her and had many good things to say about her personality (these people have been edited in previous biographies.) There are no new stunning insights to this story, but the book is good for the last chapter alone, which meticulously details the way Ted and Olwyn mishandled and maligned Sylvia's estate in a desperate attempt to recover Ted's name. It's interesting, and also quite immature: no one needs a biography to place blame on Hughes. His philandering is common knowledge and it's clearly a problem that he never honestly addressed in his life. (He cheated on every woman he was with). Is he fully responsible for her demons and her death? No. Is he a scumbag of the highest caliber? Yes. Did he abuse her? You’ll never convince me otherwise.
Anyway, the only annoying thing about this book is the CONSTANT attempt to align Plath with Marilyn Monroe. It starts from the first sentence and it does not stop throughout the book. I found myself cringing every time I read it. First, it's a false analogy logical fallacy: they may share some traits, but they are not the same woman, by any means. Also, it felt kind of sexist: "Look! All beautiful women self destruct and need love! Look, they are all the same!" With the writer's ability to make parallels to Monroe in every small respect, I guess that I am just like Monroe too, and Plath, and Scarlett O'Hara, and Susan Sontag, and any other histrionic woman that the biographer wanted to compare her to. Finally, these comparisons really perpetuate both the Monroe and Plath mythologies, and it seems that a biography should be humanizing rather than continually mythologizing. Plath did enough self mythologizing in her own work, she doesn't need a biographer to do more of it.
Rant aside, it's a good book, and it seems accurate in most respects. A much more whole picture than any others I've read. Especially, Stevenson's horrendous Bitter Fame.
