I think it's very good.. Exciting from the beginning and believable characters. However, one thing that really puzzled me, why did the main character Nancy & her friend Hayley have old style flip phones in the beginning? I kept thinking is it supposed to be miid-nineties? The cars (always a reliable indicator of when stuff is set ) were 2016 plates. Then suddenly they had iphones.. A small niggle but it's really bugging me! Any ideas?
