Sarah is at odds with herself the entire novel, as though creating two personas has stretched her thin and she is trying to reason herself back together. To prove she is more than a shell of a person, that her life matters.
I loved the format of the book, a blog post at the end of each chapter, which is attached to the emotion or turmoil of the chapter it belongs to. In this way, we are at the point of view of both Sarah and her 'other self' Mitzi. The same, but different. Her posts on motherhood, on women, all of those hit home with me. They made me like Mitzi, while still understanding why those whose lives she had misappropriated would be furious.
I was on the edge of my seat at the end. Comprehending Sarah's need to document her life, to ask questions and try in her own way to make sense of a world always at odds with itself. But also, feeling her emotions as she began to realize how wrong she had been. How words were powerful, both in good and bad ways.
Like Sarah, the end of the book leaves us with questions, while tidying up some of her life. The book needed to be this way, to stay true to the message. This is "real" life, where you will never have all the answers. Where we have to learn everything is not always about us, that there are others in this life too. I will not spoil the ending, but it reached a conclusion that made sense to how Sarah needed to say goodbye to Mitzi.
This book is a juxtaposition. A book both funny and emotional. Sarah's blog being both a strength and a weakness. Somewhere for her voice, but speaking to the wrong people. She is both heroine and villain. You like her, you understand her, but you hate her for revealing that this is all of us. We all judge others, envy others, compartmentalize others, and mistake others; so we can feel more real, more whole, more worthwhile, and like we are important. And we are, but so is everyone else.
