To Hunt a Sub

to hunt a subTo Hunt a Sub

An unlikely team is America’s only chance

The USS Hampton SSN 767 quietly floated unseen a hundred fifty-two feet below the ocean’s surface. Despite its deadly nuclear-tipped arsenal of Trident missiles, its task for the past six months has been reconnaissance and surveillance. The biggest danger the crew faced was running out of olives for their pizza. That all changed one morning, four days before the end of theHampton’s tour. Halfway through the Captain’s first morning coffee, every system on the submarine shut down. No navigation, no communication, and no defensive measures. Within minutes, the sub began a terrifying descent through the murky greys and blacks of the deep Atlantic and settled to the ocean floor five miles from Cuba and perilously close to the sub’s crush depth. When it missed its mandated contact, an emergency call went out to retired Navy intel officer, Zeke Rowe, top of his field before a botched mission left him physically crippled and psychologically shaken. Rowe quickly determined that the sub was the victim of a cybervirus secreted inside the sub’s top secret operating systems.  What Rowe couldn’t figure out was who did it or how to stop it sinking every other submarine in the American fleet.

Kali Delamagente is a struggling over-the-hill grad student who entered a DARPA cybersecurity competition as a desperate last hope to fund a sophisticated artificial intelligence she called Otto. Though her presentation imploded, she caught the attention of two people: a terrorist intent on destroying America and a rapt Dr. Zeke Rowe. An anonymous blank check to finish her research is quickly followed by multiple break-ins to her lab, a hack of her computer, the disappearance of her three-legged dog, and finally the kidnapping of her only son.

By all measures, Rowe and Delamagente are an unlikely duo. Rowe believes in brawn and Delamagente brains. To save the America they both love, they find a middle ground, guided with the wisdom of a formidable female who died two million years ago.

Quote from author:

What sets this story apart from other thrillers is the edgy science used to build the drama, the creative thinking that unravels the deadly plot, and the captivating prehistoric female who unwittingly becomes the guide and mentor to Kalian Delamagente as she struggles to stop a madman from destroying her life.

What readers say:

This book grabbed my attention from the first chapter, actually the first paragraph. The intrigue is great and even though I have no idea what all the computer based information is about, it does not detract from my ability to follow and really enjoy the book, because the author is able to incorporate that information in the writing, without over loading the reader. Hope there will be a sequel to this. Finally, despite my desire not to lay the book down (or Kindle in this case), I do have things I must do but am able to easily pick back up and continue reading without have to backtrack. That is the quality of a good book!!


Lots of action, suspense, and twists


J Murray’s long anticipated thriller, To Hunt a Sub, is a satisfying read from a fresh voice in the genre, and well worth the wait. The time devoted to research paid off, providing a much appreciated authenticity to the sciency aspects of the plot. The author also departs from the formulaic pacing and heroics of contemporary commercialized thrillers. Instead, the moderately paced narrative is a seduction, rather than a sledgehammer. The author takes time rendering relatable characters with imaginatively cool names like Zeke Rowe, and Kalian Delamagente. The scenes are vividly depicted, and the plot not only contains exquisitely treacherous twists and turns, but incorporates the fascinating study of early hominids, and one ancestral female in particular who becomes an essential character. The narrative might have benefited from language with a crispier, sharper edge, but that is purely my personal taste and preference, and takes nothing away from the over-all satisfaction of this novel.


Timely. I haven’t heard of a highjacked submarine, but the blueprint in this book could work!


A nuclear sub goes missing and Zeke Rowe is called in to help with the investigation. He joins forces with Kali Delamagente, the developer of an AI named Otto whose unique ability is compiling clues and finding things – like ancient people, kidnappers, and modern subs. Rowe’s not the only one whose interested in the subs or Otto’s capabilities. Bent on destroying America, a terrorist is making Kali’s life miserable, breaking into her lab, hacking her computer, and making hostages out of those she loves. As the terrorist ring closes in, time is running out and the stakes are rising.

One thing I enjoyed about this read is the technical reality Murray created for both the scientific and military aspects of the book. I completely believed the naval and investigatory hierarchy and protocols, as well as the operation inside the sub. I was fascinated by her explanation of Otto’s capabilities, the security efforts Kali employs to protect her data, and how she used Otto’s data to help Rowe.

If that all sounds like too much science, the characters are also well-rounded human beings with colorful histories and rich emotional palettes. There’s a little romantic attraction thrown in for fun though it isn’t a main focus of the story. The plot is high energy and complex with twists that require the reader to pay attention. To Hunt a Sub is an entertaining novel for anyone who enjoys military thrillers.


Can’t wait for the sequel!



Sample chapter:

Three days before present

Ten hours and thirty-seven more minutes and the crew of the USS Hampton SSN 767 would be home. Seasoned submariners, the six-month covert intelligence-surveillance-reconnaissance tour down the eastern seaboard of South America had gone flawlessly and silently. The Atlantic is a large ocean and the Los Angeles-class sub’s noise footprint small. Once the boat cleared Cuba, the crew would relax.

The Captain sipped the morning’s fourth cup of burned coffee when the hair on the back of his neck prickled. He glanced around, trying to identify what bothered him.

“Captain,” the Watchstander’s gaze bobbed from the Executive Officer to his watchstation. “Navigation is non-responsive.” Confusion tinged his words.

That was it. A change in the deck’s subtle rumble. Before the Captain could react to the impossibility that guidance controls had crashed, every monitor in the sub’s nerve center shut down.

He hadn’t seen this in twenty years of driving subs. All personnel made a hole as he rushed toward the Control Center, shadowed by the XO.

“Sonar readings?” The Captain called to Sonarman Second Class Andy Rikes in the compartment just aft of Control, barely larger than a broom closet but elbow-to-elbow with operators, fingers flying across keyboards and eyes locked onto screens that blinked a dull grey.

Rikes answered, “Negative, Sir. The hydrophones are working, but aren’t sending raw data, like someone pulled the plug and flushed everything out to sea. Trying to fix it.” His voice was hopeful.

If the screen had worked, Sonarman Rikes would have seen the ping, a final gasp before everything electrical collapsed.

The COB—Chief of Boat—interrupted, “Captain. Reactor Scram!” The sub’s nuclear power had evaporated. “Nuclear technicians isolating the problem. Battery back-up is being attempted.”

“Shift propulsion from main engines to EPM,” an auxiliary electric motor that could turn the propeller.

“Negative, Captain. Non-responsive.” Fear leaked from his voice.

The depth meter no longer worked, but the XO guessed that the sub was angled downward at 10 degrees

“Blow main ballast tanks!”

“No response, Captain.”

“How deep is the ocean floor in this sector of the Atlantic?”

The Sonarman answered, “It varies between 1,000 and 16,000”

16,000 feet was well below the sub’s crush depth.

“There are seamounts and ridges spread throughout. We could get lucky and land on one. Or not.”

“Inform US Strategic Command of our situation.”

“Sir, comms are down.”

“Release the message buoy,” though all that told the world was they were in trouble. It could quickly drift miles from their position.

The Captain continued, voice calm, face showing none of the worry that filled his thoughts, “I want all department heads and Chief Petty Officers in front of me in five minutes. I want the status on every system they own and operate. Wake up whoever you need to.” He had a bad feeling about this.

“Gentlemen, solutions.” The Captain looked first at XO, then COB and finally NAV, the Navigation Officer who turned to the senior chief of navigation.

“It’s like an electromagnetic pulse hit us, which can’t happen underwater…” then he shrugged as though to say, I have no idea, Sir.

They practiced drills for every sort of emergency, but not this one. No one considered a complete electrical shutdown possible.

“We’re checking everything, but nothing is wrong. It just won’t work.”

“Where’s CHENG?” The Chief of Engineering.

“Troubleshooting, Sir.” COB’s voice was efficient, but tense.

The Captain didn’t wait. “Condition Alpha. Full quiet—voices whispers, all silent, no movement not critical. Defcon 2,” the second-highest peacetime alert level.

No one knew who their enemy was or why they were under attack, but they had one and they were.

“XO, get lanterns up here.”

Within an hour, the massive warship had settled to the ocean floor like the carcass of a dead whale. It teetered atop an ocean ridge, listing starboard against a jagged seamount, and the gentle push of an underwater current from a cliff that plunged into a murky darkness. Every watertight door was closed. As per protocol, the oxygen level was reduced to suppress a fire hazard. Without climate controls, the interior had already reached 60 degrees. It would continue dipping as it strove to match the bone-chilling surrounding water temperature.  Hypothermia would soon be a problem. For now, though, they were alive.

The hull groaned as though twisted by a giant squid.

The Captain peered into the gloomy waters that surrounded the sub. “Thoughts, XO?”

“We’re stable for the moment, barring a strong underwater current.”

Based on the creaking protests from the hull, they were at or beyond crush depth. Any deeper, the outside pressure would snap the HY-80 outer hull and sea water would roar into the living compartments. Everyone would be dead in seconds, either drowned or impaled on the ragged remains of the sub by a force in excess of a Category Five hurricane.

“We’re beyond the depth of the Steinke Hoods,” escape equipment that included full body suits, thermal protection, and a life raft. Budget cuts had eliminated funding for more advanced solutions.

XO pointed toward a darker expanse of black just yards from the sub. “No telling how deep that crevice is.”

“Gather the crew in the Forward compartment. Seal all other compartments. Ration water. Start O2 candles when levels reach 50% normal. Did the message buoy launch?”

“Yes, sir.”

That was a relief. The Deep Submergence Rescue Vehicle (DSRV) deployed in emergencies from shore couldn’t assist if it didn’t know they needed help.
