This is a fast paced - action - suspence book about finding a terrorist before he finds John Corey and his wife. Both of whom have hunted this terrorist (the Lion) in the past.
The Coreys like to sky-dive and go up with a bunch of people to do formations etc. Well, on the way down someone grabs his wife and tries to kill her, guess who? ...the Lion
And thus begins the action.
Very good, and by the way, I hate terrorists.
