The artwork on the cover and description of the book peaked my interest. Reading for fun is not my go to activity. When I read it is typically something work, nutrition, fitness, or psychology related. So I was willing to give this Rollins novel a try since BLOODLINE captivated me to a point that I read the entire book over a 24 hour period. The character development, spec ops component, and the chase sucked me in. I still think about that book and feel like I watched a movie because I can vividly recall many of the scenes in my mind. Blood Gospel did not grip me the same way. I found the first couple of chapters interesting but not to a point that I would make time to sit and read. The development of the two primary characters while done well wasn't drawing me in to the point where I wanted to know what happens next. In BLOODLINE I couldn't wait to see what death defying encounter the special operations canine, Kane, would beat next. Yes, even the dog in BLOODLINE was a character I couldn't stop thinking about. I will probably finish the book someday or maybe come back to it. For me it is clear that reading for entertainment, I need to look into another novel from the sigma series.
