I was SO excited and grateful to get this Arc from NetGalley! This is not my "normal" genre, but I adore anything written by Casey McQuiston. The whole story idea was intriguing. I loved the premise of Shara disappearing and leave a trail of clues for only a select few people to find and figure out. The main characters were what cemented my love of this book though. While trying to understand who Shara really was, we got to know Rory, Chloe and Smith; and they got to know themselves better as well. I keep thinking about these 4 people and wondering what they are up to. I want to know more about them, to go on another adventure with them, to see them grow into themselves more. I really hope Casey writes a spin-off! Maybe it can be centered around Rory and Smith this time!
