Showing The King of Plagues by Jonathan Maberry

Joe Ledger, ex-cop and now special forces killer, must lead his elite team against a criminal mastermind who threatens to unleash a super plague that could wipe out humanity.

After dealing with zombies and genetically-modified monsters, Joe Ledger was hoping for a break. But in the world in which he lives, evil is only just around the corner. His job is to protect the world from maniacs, maniacs who often have resources and support that his team doesn't.

Frenetic pacing, thrill-a-minute adventure, breath-taking and realistic (author is a seventh Dan Karate black belt) violence. Perfect for the male readership.
