There are literally hundreds of Plath biographies out there but this is really the one to begin with. Steinberg painstakingly details every aspect of Plath's life without heavily weighing in with personal commentary or jaded viewpoints- it's as accurate and stark account of what happened as any other book out there, perhaps more chilling because of the detached voice. It allows the novice reader to decide for themselves, to give this narrative meaning. More importantly, what this book accomplishes that no other biography does is tie Plath's poems to specific events and places significant to the poet. The book is not just a progression of her life but a progression of her work as an author as well. Be sure to check out Steinberg's website, A Celebration, This Is which adds a whole other layer of depth as he painstakingly visited and photographed nearly all of the places mentioned in the book.
