What a page turner! I will definitely re-read this one.
Basic premise: A woman finds herself in a park surrounded by bodies with no idea who she is or what just happened. However, there is a note in her pocket from herself, giving her a name and explaining what to do next. Thus is she thrust into the middle of a mysterious plot.
I did find some of the letters written by the old Thomas a little off in tone from the characterization of her. Other than that I loved this!
