Patient Zero

Baltimore detective Joe Ledger just killed a terrorist he already killed last week. His aim was perfect both times, which leaves only one impossible answer, and it drags him off the street into the Department of Military Sciences, a secret unit built for threats Homeland Security cannot handle. His first mission is a nightmare made real: a terrorist cell is ready to release an engineered plague that kills its victims and brings them back stumbling, ravenous and contagious. Ledger is a hardened fighter, but no training prepared him for the dead getting up to kill. Now he must hunt living men who have learned to use death itself as a weapon.
