It started out fine, but our hero is a putz. Taxi driver should never have been ignored. Happens to go to Haj where millions gathered. Come on. What really galled me is the cold blooded ness of when he finds Jill. And succeeding on sub to survive, that should have been communicated right away to lab so could be desseminated. Ordeal of his children was dreadful. Started out okay, but became too virulent and died. Very disappointed as I loved “Looming Tower.”
