    I have loved the these thrillers since the beginning looking forward to the next one when it comes out.

    Have the sisters stopped writing? I will admit the confusion of Nina was having with Paul and what’s his name and what she wanted to do with her life while her son is growing up was getting a little unbelievable–especially Paul’s antics and the long distance romance didn’t add anything to or for Nina either–how about getting away from the personal and getting into what a lawyer of Nina’s expertise can do. The personal, IMHO, doesn’t add to the character and makes continuing the series difficult because it seems they become unbelieveable.
