I really struggled with this book. I almost DNFed at 25%. Ultimately, I did finish it, and I am glad I did because I think the final act was my favorite part of the story. However, I think the title and cover set me up with expectations of what this book would be which were very different than what the book actually delivered. This is not science fiction- despite the fact it was nominated in the science fiction category in the Goodreads Choice Awards. It is only barely speculative. This is a book about grief, depression, and parenting a baby and then a young child as a single mom struggling with loss and borderline alcoholism. There were passages of the book which struck hard, individual observations and lines which rang like bells. There is also nearly no plot and I was frustrated by the lack of world building. I wanted to know more about the laws governing extra shadows- were Shadesters allowed to vote, hold passports, travel across state lines? Had anyone experimented with the removal of Shadows? When and how did cameras get installed in apparently every home in American, and how did the government hire and pay for a workforce of seemingly 1:1 surveillance agents to citizens? Also, how on earth did Kris manage to pay for a whole apartment on a single salary working a call center job, especially when as a Shadester she had to pay extra taxes? I understand that this is literary fiction, and these questions are obviously not the ones the book was interested in answering. But it felt strange to me that a book so focused on parenting would not include a single passage about struggling to pay for or arrange childcare. The "pop quizzes" that break up the text did not work well in audio, and did not add anything to my experience of this book. Ultimately, I would only recommend this novel to a vary narrow audience of readers who enjoy lit fic, and are willing to spend a lot of time in the POV of a character teetering on the edge of a mental breakdown through much of the story.
