“Greaney knows what military action fans want and delivers in spades.”

“”The latest in the Gray Man series continues to demonstrate why Greaney belongs in the upper echelon of special-ops thriller authors.”

“Mesmerizing…”

“Equal parts revenge drama and conspiracy tale, Mission Critical combines the best of John le Carré and Robert Ludlum. Greaney has fashioned a masterpiece of an action thriller, mixed with deep-seated global politics, placing him on level footing with the likes of Brad Thor, Brad Taylor and the late, great Vince Flynn.”

providence journal

“This novel is vintage Greaney,”

“with a tight plot, a ticking clock, and a sympathetic antihero…This is good, Clancy-esque entertainment. May the evildoers of the world have nightmares that Violator becomes a real person.”

kirkus reviews

“A protégé of the late Tom Clancy, Mark Greaney writes spy thrillers that crackle with excitement and are packed with rigorously researched detail that makes the stories startlingly realistic. In Greaney’s eighth Gray Man adventure, CIA assassin Court Gentry fights to stop a series of deadly attacks against American intelligence around the world. Meanwhile, a former Russian spy aspires to world domination with the aid of a bioweapon perfected by a rogue North Korean scientist. The gloriously pulpy dialogue and white-knuckle action make Mission Critical a great read for your next cross-country flight.”

“At the start of bestseller Greaney’s exciting eighth Gray Man novel (after 2018’s Agent in Place), CIA contract agent Court Gentry (aka the Gray Man), who has received a last-minute summons to Langley, is picked up by a CIA Gulfstream in Zurich. The plane stops in Luxembourg City, where a team of CIA agents boards with a hooded prisoner. The next stop is an English air base, where the Americans are to hand over the prisoner to MI6. On landing, gunmen mow down the two transaction parties on the tarmac, grab the prisoner, and drive him away in a van. Court pursues the van in a powered glider he commandeers. Meanwhile in the U.S., Court’s love interest, former Russian intelligence officer Zoya Zakharova, is being questioned at a CIA safe house. When the safe house comes under attack, Zoya is the only one in the house to escape. The two assaults are related, as revealed in between the many intense scenes with even higher high body counts that follow. Greaney knows what military action fans want and delivers in spades.”

Mission Critical
CHAPTER ONE

While an evening rain threatened outside, inside the well-appointed three-car garage gym a woman worked out alone. With her shoulder-length brunette hair tied in a ponytail, a blue American University T-shirt, and gray yoga pants, she did push-ups and crunches, pounded and kicked a heavy bag, and slung dumbbells, all before heading over to the climbing ropes.

The garage ceiling was just ten feet up, so the ropes weren’t very high, but they were three feet apart and a challenge to climb. The woman grasped them both with gloved hands and began ascending, one hand grabbing and pulling while the other slid up the opposite rope to a higher position, then closed down in a viselike grip to heave her body higher.

Her arms and back and shoulders did all the work; she let her feet hang, swinging back and forth as she climbed, using her upper body for power. At the ceiling she shifted both hands to the same rope and climbed down.

Immediately she started back up again on both ropes.

While she worked out, a muscular bald-headed man in a Windbreaker and cargo pants looked in on her from time to time from his position on the driveway. He wore a Beretta pistol on a utility belt around his waist, as well as handcuffs, Mace, and a radio. Beyond him in the woods another man strolled with a rifle across his chest.

As the woman dropped down after her fourth time up the ropes she doubled forward and put her hands on her knees, struggling to catch her breath.

The bald man on the driveway chided her. “Suck it up, snowflake! Back at BUD’s we had to climb a rope three times higher, five times, after about a thousand push-ups.”

She faced away from him, but she took one hand off a knee and flipped him the middle finger over her shoulder.
