I really like Tess Gerritsen's stand alone books. They are wonderfully suspenseful; the mystery is intricate; and difficult to decipher. I liked lawyer David Ransom from the beginning and his attraction to Dr. Kate Chesne was immediate and obvious. Kate was a good person and I really felt for her. It's got to be difficult to cope when you know you are being set up and yet no one will listen. I enjoyed David and Kate's investigation and the danger level was real and believable.
