To be honest, I had to seriously ask myself whether this book didn't belong in the "YA" category. Here's why I say that:
1) The main character had everything come too easily.
2) The whole "orphaned main character" was done in a cliched manner that didn't evoke any real sympathy from this reader.
3) Characterization was middling at best; Laura's girlfriends, for instance, were practically carbon copies of one another, and Laura herself was only set apart by her quirky panic attacks.
4) The romance seemed contrived--she was "pretty," and since the hot, young lawyer didn't have anything for the other single ladies in town, it was obvious that they'd "fall in love."
5) Any sense of suspense was killed early on by Laura's frequently-discussed paranoia and panic issues. While those episodes lessened considerably, later in the story, the early parts of the tale created a "boy who cried wolf" feeling that hurt the build up of tension.
6) Apparent reliance on old thriller novels for plot devices didn't give the book much of a feel of originality.
5) Details were a used bit too liberally in certain places, such as conversations, and were an occasional distraction from story flow, despite serving to increase the level of realism a touch.
6) Plot devices and logical questions were either sidelined with a mere nod at the issue from a character, or just plain ignored, but were left unresolved more often than not.
7) The prose was fine, and story flow was okay, but, again, I never got a sense of rising tension. Even when Laura's car's brakes were tampered with, she got out of that with only minor injuries (that scene had another one of those logical questions). The "rising tension" seemed to be forced on the reader by a somewhat arbitrary deadline.
8) The murder investigation seemed a bit on the juvenile side, given the way it was conducted, and given the ease with which it was conducted. It seemed to be more a method of filling pages than of actually advancing the story much.
I'll admit I haven't read too many thrillers, but this one... didn't do much to thrill me.
