This one may be closer to 3.7 than 4 stars. The mystery, while solid, felt a little more confused. Probably because I wasn't a fan of the "Then" chapters. Not that they weren't good in and of themselves, they were. I just wasn't a fan of the back and forth storytelling. I never have been. And it also may be because I live for Russ and Clare's relationship. That is what really made this book, and I'm left with way too many feelings that I won't get into here. I just need to start reading the next book ASAP.
