When the only option is to maneuver a crippled plane into the calm eye of a category five hurricane

In the Atlantic Ocean, Hurricane Helena is gathering strength, becoming the most powerful storm in recorded history. As Helena bears down on Bermuda, Donovan Nash, along with other members of the scientific research organization Eco-Watch, are called to fly in and extract key government people who have been studying Helena.

For Donovan, the routine mission turns deadly when an attempt is made on the life of the lead scientist. A woman from the past, Dr. Lauren McKenna, is suddenly thrust back into his life. With 300 mph winds and waves over 90 feet, Helena marches relentlessly for the vulnerable east coast of the United States.

In a bold attempt to diffuse the power of the hurricane, Eco-Watch is called upon to conduct a final flight above the massive fury, where the jet suffers a catastrophic engine failure. Now the only option is to maneuver the crippled airplane into the calm of Helena's eye.

Has Donovan Nash gone mad?

Donovan Nash is a man under siege, and this time it's personal. Eco-Watch, the premier scientific research organization he founded, is being blamed for a series of violent eco-atrocities that ignite protests around the world. Behind the attacks is Garrick Pearce, a man from Donovan's past, who is bent on a ruthless vendetta. Garrick has promised that after he annihilates Eco-Watch, he'll murder everyone close to Nash.

Recoiling from the damage, Donovan enlists the help of Erica, a woman who claims she has information Donovan needs, but her knowledge makes her a marked woman. Running from trained killers, the FBI and even his own organization, Donovan races from Southern California to British Columbia, then finally to Alaska where he joins Eco-Watch personnel and desperately tries to stop what promises to be the worst eco-atrocity in history.

With his world in tatters and everything he built seemingly destroyed, Donovan is forced to make one last desperate gamble to stop Garrick and silence the man forever—a roll of the dice that may very well cost Nash his life.

A story of love, loyalty, and how far Donovan Nash will go to rescue Lauren . . . and save hundreds of thousands of lives

A CIA-operated jet on a clandestine mission disappears in Eastern Europe. No mayday, no wreckage, and no known survivors. No way to know if the top-secret extraction of a key American scientist from Slovakia, or his liberator, Dr. Lauren McKenna, code name Pegasus, are dead or alive.

Donovan Nash’s precarious world is rocked when word reaches him that his wife, Lauren, is missing in Eastern Europe. Using his millions, and fueled by the fear of losing his wife, Donovan and company cut a swath through Austria and Hungary.

Desperate, Donovan leverages his lifelong secret to enlist an unlikely ally―one of his oldest friends―who may very well want him dead. As Donovan closes in on the truth, another, and more deadly, reality is revealed. A ruthless terrorist group has acquired a stealth aircraft with the ability to deliver a nuclear device. They are poised to strike―but where?

What started as a rescue turns into a full-throttle aerial chase. Will Donavan be able to rescue his wife, as well as prevent a nuclear catastrophe?

Donovan Nash’s good deed leads to terror with horrifying repercussions

While on a routine Eco-Watch flight above northern Canada to study one of the most powerful solar flares in history, Donovan Nash and Michael Ross narrowly miss colliding with another aircraft―a Boeing 737 that’s not supposed to be there. With the mysterious 737 trailing smoke, Donovan and Michael watch as the stricken aircraft makes an emergency landing on a frozen lake.

As the Boeing breaks through the ice and begins to sink, a figure escapes into the frigid water and manages to climb up onto the ice. Donovan reaches the lone survivor and discovers it’s a young woman. Just before she blacks out, she whispers a dire warning, “Don’t let them know I’m alive―they’ll kill everyone.”

Seconds to Midnight plunges Donovan Nash and the Eco-Watch team into a fight for their lives. While Donovan searches for answers at the bottom of a frozen lake in Canada, his wife, Lauren, runs from operatives embedded in the top levels of the Russian Government.

With communication in the Northern Hemisphere crippled by the massive solar storm, Donovan, Michael, and Lauren battle for each second—as the clock ticks toward a possible Armageddon.

Unrelenting showers of meteor fragments hit Northern California—massive fires—power grid failure—millions at risk


Hundreds of white-hot meteor fragments plunge toward Earth near Monterey Bay, California. Huge fires ignite the tinder-dry landscape and, as the sun sets, the power grid collapses and the fires grow, illuminating a nightmare created in hell itself. Donovan Nash realizes he is trapped.

Injured and growing desperate, his options dwindling, Donovan fights to keep himself and a small band of survivors alive until dawn, when they can make one last attempt to escape the inferno.

Meanwhile, Donovan's wife, Dr. Lauren McKenna, working with the Pentagon as well as the Forest Service, envisions a bold approach to stop the fire from spreading all the way to the Bay Area and the seven million residents living there. She's terrified that, if not executed perfectly, her plan could cause the death of thousands of people—including Donovan.

In the style of Clive Cussler, best-selling author Philip Donlay climbs to a new height of terror in his 8th Donovan Nash thriller
