The Smallest War: an action-adventure thriller

I was looking for something a little different to the usual "whodunnit" genre that I read so I thought I'd give The Smallest War a go. Wow! So glad I did. The story is a slow burn as the intrigue gains momentum and characters and concepts are developed. The action then unleashes like a tornado and had me on the edge of my seat as the story thundered towards the thrilling climax. I understand Mark Sheehan has a second novel in development....count me in!
