Wow. There's a lot to say about this book. It would actually be a great book for discussion, but it is pretty disturbing and graphic, even as someone who reads a fair amount of graphic content. I recommend reading the author's additional info at the end for a good explanation of why the murder scenes were so visceral. I especially appreciated the historical settings throughout this book. You get to see Chicago in so many points in history: the Red Scare, pre-war and post-war society, the weeks leading up to Roe v. Wade, and more. 

This book is being adapted to a series with Elisabeth Moss (and Phillipa Soo as one of the Shining Girls), and I am definitely intrigued to see how deep they get into the different characters. Would make a very interesting series.
