Ms. Maxwell masterfully read this medical thriller/horror story. She read in such a way that it was easy to get caught up in the events of the story. The story was fast-paced. It moved along without ever bogging down. Tranquility Maine wasn't tranquil for long, that's for sure! A most satisfying story-well constructed and scary. This was my first book by Tess Gerritsen and I am looking forward to reading more of her books.
