Usually I love Tess Gerritsen, I have most of her books which I have rated 5 stars. However, this one seems almost as if it is written by a different person, the plot is ok but some of the script she uses is so overused it's like listening to a manufactured pop song. Maybe this one was written a while ago and the publishes decided to cash in on her recent success, I don't know but I'm hoping her next book is better than this. It's not terrible, don't let me put you off, but it's certainly not her best.
