Too much emphasis on the unbelievable abilities and toughness of the main character, I did not like Charles Angels or the Bionic Woman, which took away from the story line. I struggled to get to 20% of this book due to this and the mystery did not really develop until 70% of the way through the book. I did read until the end and was disappointed overall. Maybe for others but too slow for me. I have rated as a 3 but only just. No serial killer was evident until late in this book. It was more about the main characters life.
