I thought this was a solid read and think it was probably 3.5 stars. The hook was brilliant - friends skyping and then one is called away to the door and never comes back - that really caught my attention. The writing in the first part was pacey and kept my interest. Then part two came along, ten years after Lillian had disappeared, and we got a whole load of backstory about everyone and the focus on finding out what happened to Lillian was lost. I felt the book lost its way a little in the middle, but then the end came in a whoosh of action. Ned, the policeman seemed to make discoveries in an instant, that he had overlooked in the first investigation ten years previously and I couldn't work out how he'd made the leap in thinking. For me, there were a few too many cliches and I never felt I got to know the main characters very well. Ned's life was a bit tiresome, at times and I felt it got in the way of the story. And there were too many instances when things were just bumbling along and then something significant suddenly happened, in a sentence or two. I would have liked more of a build up to these events, so I could feel them more. But throughout the book, I didn't feel emotionally involved at all. Still, a good tale with an exciting ending.
