Many plot are woven into this third book,of Cold Harbor series. A murder of a student who took a class from Maggie, is that the connection of why the killer is after her. Learning about hacking into computers, and how they can get controlled of a car, was something scary. As the Blackwell Tacktical come to protect her, they are trying to uncover the why, the answer isn’t coming. Yet, the killer is determined. Amidst the twist, is the side of grief, that Maggie and Jackson share, from five years before, a little too much, of going over and over it, I thought. This is another page turner, and will definitely kept readers reading, and looking for more in the series.
