I loved the story line and the point of view from the 2 girls. It was well written and I was looking forward to finding out what the clues meant and which were the red herrings. Very disappointed in the cliff hanger ending. I know it is a marketing tool but I only read a book every few months and even if there is a followup book, I like to have the ending in the book I am reading without having to go buy the next book just to find out what happened. I suspect the other books may be the same and to find out the end of the current book you have to buy the next one. Probably not going to do that, even if I went hunting for the next book(s).
