Thank you @stmartinpress @macmillan.audio for a copy of this. I was expecting a thriller, a mystery of a missing baby but didn't get it in this book. The opening line for this book started so strong and I was invested. This book focuses more about childhood friendships that drift apart as you get older. Cassie is a micro influencer and her former BFF has been left in behind because she doesn't want children. Billie is desperate to maintain their friendship as see her friend only online. There really isn't any mystery with the baby missing so I was a bit disappointed with it. I did enjoy seeing their friendship flashbacks and their complex relationship. I did enjoy the dual narration between the two characters.
