The Point Man - Steve Englehart
Max August was a point man when he served during the Vietnam War, the guy who had to lead his patrol through dangers he couldn't possibly anticipate. Now he's a disc jockey, at one with the music and his faithful audience . . . until the day when he is swept into a battle invisible to all but the participants.
For nearly five centuries, Cornelius Agrippa has fought against an evil that has threatened to corrupt and destroy everything good and untainted in the world. Now, Max has joined the battle. It wasn't his idea to fight a demonic entity that can become anything it wants: an undying monster or the most desirable woman in the world. Max has been chosen by fate to fight those who would use magick to destroy freedom and wreak havoc on an unsuspecting world. Along with Agrippa and Valerie Drake, a beautiful, talented singer, Max is the only hope of the free world.
