With the lives of sixty-three of his friends and business associates snuffed out in one horrifying blink of an eye, the wealthy and enigmatic Jonathan Strickland boards a dangerous roller coaster ride of a lifetime in this clever, nail biting who-done-it. From a clandestine meeting in the foreboding Syrian desert, to a brazen gun battle among the rich and famous in the exotic streets of glamorous Miami Beach, and then onto the discovery of the secretive Catskills hideaway of a reclusive scientist in upstate New York, the thrilling ride never lets up. Strickland races against time to find the invisible killers who have even more horrific carnage in mind; they call their sinister plan the Joshua Effect.
