captivating, yet disappointing

My first book of Carlene Thomson: and it is a rather expensive thriller.
Would probably suitable for filming when the end would not be quite so far-fetched.
I stayed as a wife and mother at the ball as it comes to endangered daughters. I read the book almost in one piece, because the threat comes across very well, but knew about from the middle who have "the evil" is at the end and felt exhausted and unsatisfied.
While standing on the cover, but you can not really compare with Mary Higgins Clark.
