I find it extremely difficult to explain my feelings about this book. It is not really a mystery and while it covers the paranormal there is not much action on it in the story. I recommend reading at least one previous book to understand the rationale of the characters. The information on the early research of the way the brain works is informative and well researched. I found it intriguing.
Abby Kimball and Ned Newhall have the ability to see the ghosts of dead ancestors. They decided to do a scientific study on the phenom. They need a larger study group of the five known persons with the ability. All are related to each other. Ned will be in charge of the science tests and Abby the biological parts. Abby goes to a couple of spiritual events hoping to find additional people with the ability. She finds Susanne who reacts to her touch. Ned enlists the assistance of a friend who is working on a map of how the brain works. They agree to be tested and the result startled all the parties. I am looking forward to the next book and I recommend this book and series.
