This was a fairly fast-paced thriller, following Lydia, a forensic photographer, as she takes on her biggest case yet. A couple have been found brutally murdered at their campsite, photographed, and staged for the police to find. The killer has also left a message that Lydia seems to connect with. 
I found the story, the characters, and their backstories interesting, and it certainly helped understand their thought processes and their actions. There were moments where I hoped I was wrong about what was going to happen, but it did. Because of that, I was incredibly angry at the way this book ended. More angry than I can put into words, which is why I marked it down.
