This was dark and twisted, but I called the ending pretty early on which made it lose some of its power. (The killer has to be someone they know, there are a limited number of characters, from there it's basic math.) But even despite that, I had a good time reading it. It was dramatic and chilling and terrifying, though I had trouble connecting to it as much as Lisa Gardner's newer books. Still a good read and leaves me happy as ever to continue with her books.
