Disjointed and almost poetic, Sarah Gerard (a sufferer of an eating disorder herself) writes from the perspective of a woman suffering from anorexia, and her struggles with her mental state, her parents and mainly her distant boyfriend who is an alcoholic.
Extremely dark and uncomfortable, it was almost painful to read, which I think added to the depth of the story - but is also why I can't decide whether I loved or hated this book. The title stems from the poetic nature of the book, using metaphors to liken the main character's experiences with astronomy, which despite the issues being addressed, made it quite a beautiful read - and was a very necessary quality to break through the harshness. To be honest, I also don't think it matters whether I enjoyed this book or not, because either way it was extremely powerful, and I think Gerard was successful in her mission.
This book definitely needs a trigger warning for sufferers of depression or eating disorders. It was really, really gritty. So if you are planning to read this book, prepare to feel uncomfortable, as it as not at all for the faint-hearted.
I am glad I read Binary Star. It is so outside my realm and not an issue I am at all close to, yet it was impactful and left an impression on me.
