Katie and Leblanc have to search for a serial killer that keeps on killing people in the US and Canada, they have difficulty defining what is the link among the several dead and follow many leads under a lot of pressure to find the culprit. While trying to capture the killer they help put behind bars other culprits responsible for lesser crimes. Although I gave this story 4 stars, it should really be 3,5 stars. There are too many repeated thoughts made by the two FBI officers which made, sometimes, - at least for me - the story slow-paced.
I received a free copy of this book as a member of the author's ARC team, and this is my honest opinion.
