With an explosive beginning, this book held a lot of promise and I ended up finding it a very readable, twisty, enjoyable story. We get a lot of perspectives in this one, as we find out from each of the murdered family members what had been going on with them personally in the days leading up to their deaths- and there is so much potential for the true reasons they were murdered. There were some elements of this story that were more chilling than others, but as dots began to connect it was a race to the finish. There was one thread that I had decided was definitely going to go somewhere, but it ended up not being used and I'm interested to read more reviews and see if anyone else thought there was a connection there that didn't actually happen. Perhaps the best parts of this were with FBI agent Keller and her supportive husband- I loved each of their conversations.
