I finished this book is a flurry, reading it for hours at a time during a short beach vacation with my family. Now, this wouldn't have been my obvious choice for a beach read (even for me, a wanna-be academic), but it was engrossing, addictive, and titillating in all the ways a good beach read should be.
As others have pointed out, Castle is honest and she doesn't soften the edges much on anyone (even herself or her current partner), but she is also gracious. In her essay on Sontag, although she spends much of the time sketching a character you're not sure you'd want to meet, she ends with a sincere appreciation for Sontag's contribution to 20th century feminism.
I have to admit, though, that I enjoyed the first re-published essays more than the longer one on the Professor. In the shorter pieces, I was thrilled by her ability to weave separate threads into one coherent piece, showing connections where you thought there couldn't be one. Her piece on the Professor worked with the same idea, but meandered here and there, trying to scoop up all of her early academia and sexual exploration/experience in to one cohesive narrative anchored by her experience with the Professor. For me, this was too much; I felt bogged down with too much detail, and almost lost interest half way through this piece (although I was glad I pushed on as it found its momentum again quite soon). I appreciated the succinctness of her other pieces, and that, I think, was lost in this piece.
Yes, this is written by an academic, and there is no way around this. It infiltrates every page because that is who she is, and she is writing honestly and openly. It won't be everyone's idea of a good beach read, but, I have to say, I kind of like this kind of academic and can't wait to find more written by her. I'm still shaking my head wondering how I hadn't heard of her before finding this book.
