This was ultimately a less-than-great mystery, that suffered from a pretty bland ending. I did enjoy the dual timeline of the story where part of the novel told the beginning of the story, and the other half told the story 50 years after the original events. 

I was disappointed in the novel as it really didn't have a lot of mystery regarding the killer, the main characters tracking the killer down, or ultimately getting justice served on them. It was more focused on the super awkward love story of the 2 main characters and them doing NOTHING but worrying about getting caught and stuff. I started reading hoping for a cool serial killer mystery, and ended up with a story about doomed romance and regret.
