I don't know what I expected from Sadie but it was a much different book than I imagined. Crime thrillers are not really my typical genre, but this one came highly reccommended by a friend. I enjoyed Sadie herself as a character - by far, she was the best part of the book and her narration was great. I was iffy on the dual narrative structure (as half the chapters are transcripts from a podcast about Sadie and her sister, Mattie) - but I think it ultimately made the ending stronger. Wish it ended differently. I don't know. I will be thinking about it for a long time.
