When you have to kill the same terrorist twice in one week there's either something wrong with your world or something wrong with your skills--and there's nothing wrong with Joe Ledger's skills. And that's both a good and a bad thing. It's good because he's a Baltimore detective who has just been secretly recruited by the government to lead a new task force created to deal with the problems that Homeland Security can't handle. This rapid-response group is called the Department of Military Sciences, or the DMS. It's bad because his first mission is to help stop a group of terrorists from releasing a dreadful bioweapon that can turn ordinary people into zombies. The fate of the world hangs in the balance.
