Damage Control: A Jonathan Grave Thriller, Book 4 (Unabridged‪)‬

The hostages are young: a bus full of teenagers on a church mission. The ransom demands are explicit: deliver three million dollars - with zero involvement from law enforcement - or all captives will be executed. But rescue specialist Jonathan Grave doesn't believe in ultimatums. For him and his elite team at Security Solutions, it's all about protecting the innocent. Now Grave must face the chilling possibility that someone within the U.S. government has a deadly secret to protect - one that could jeopardize national security like never before.
