This is the second in a series starring Samantha Owens, a forensic pathologist. I, however, felt this book had duo lead characters -- Sam and Xander. The two of them work well together and complement each other with their viewpoints and skills. They have to find out who's behind the release of the pathogen and why.
They also have to determine whether this was a mass attack or an assassination. And heating on the back burner is the question of whether their relationship will go to the next level.
The Edge of Black is a fast read. Not because it's short, because it's not. It's a fast read because I kept picking it up and reading instead of doing other things that needed to be done. It has a lot of interesting side characters, action, twists, and just a tad of a growing romance.
I give The Edge of Black a rating of Hel-of-a-Situation
FTC Disclaimer: I did not buy this book. It was sent to me by a publicist. Unfortunately, my office looks like a cyclone hit it and I cannot find the package that it came in. Therefore, I cannot acknowledge that person. Whoever sent it, thank you. I enjoyed the book. Disclaimer #2: A cyclone did not actually hit my office. I don't think there's ever been a cyclone in central Texas. Disclaimer #3: We've had hurricanes hit the coast of Texas, but I believe a cyclone takes place over dry land, not water. Disclaimer #4: I could be wrong on that. The dry land/water thing. Not the book. I liked the book.
