A young mother tries a revolutionary PTSD therapy, only to find herself—and her family—in danger.

Living a seemingly perfect existence in Charleston, brilliant novelist Clara Swanner secretly exists in the shadow of post-traumatic stress. For years, she has been haunted by a dark event of her past—an event that has since caused four of her friends to commit suicide.

When a new psychedelic drug gains a cult following as a treatment option, Clara thinks she has nothing to lose by trying it.

But when the treatment releases a flood of memories that Clara has spent years trying to escape, she uncovers disturbing connections between her friends’ deaths. As the lines between reality and nightmare begin to blur, she isn’t so certain that they killed themselves.

Determined to uncover the truth, and grappling with her own inner demons, Clara becomes entangled in the dark and deadly mystery that unfolds. The more she faces her past, the closer she gets to proving the identity of a killer.

And the more she realizes he’s already coming for her—and her family.

Before he was an assassin, David Rivers was a patriot.

One year after the 9/11 attacks, he serves as an Army Ranger in Afghanistan.

His patrol enters the Shigal Valley, a desolate place with a fearsome reputation for enemy fighters—a reputation that David is about to experience firsthand.

As the first shots ring out over the valley, David must decide between military orders and gut instinct...and in the process, discover a hidden truth about himself.

David Rivers is an Army Ranger—a combat veteran of the wars in Afghanistan and Iraq. He has almost completed his final year at West Point when his world is turned upside down by a sudden discharge from military service. Angry and confused, David soon hits rock bottom.

And that's when they appear.

Three mysterious men. Men who know David's dark secret—they know that he has murdered someone in cold blood.

And they want him to do it again.

An avenging survivor. An unconquerable enemy. And one impossible betrayal…

David Rivers wants vengeance.

But there’s only one way to kill his greatest enemy—David must first join the secretive organization that slaughtered the only family he had.

To prove his allegiance, he enters a life-or-death battle in the badlands of Somalia.

But the closer David gets to his target, the more he realizes that the betrayal of his team was not as random as he thought.

Someone inside the organization seems to know his true purpose, and that could mean only one thing:

David might not have been the sole survivor after all.

An assassin on the brink of destruction. The leader of a global crime syndicate. And the meeting of two fatal enemies…

David Rivers killed the man who betrayed his team.

Now, he’s after the faceless mastermind who gave the order.

To the criminal world, this man is known only as the Handler.

And for the first time, he is within David’s reach.

But in order to get close to the Handler, David must first serve him. This time, the task is new: not to kill a target, but to protect one.

As David negotiates a labyrinth of twisted loyalties in the violent slums of Rio de Janeiro, he realizes that the betrayal of his former teammates was just the beginning.

And nothing in David’s murderous past can prepare him for what happens when he finally meets his greatest enemy face-to-face.

A condemned hero. An unlikely ally. And the plot to assassinate a criminal mastermind…

David Rivers’ luck has finally run out.

He’s been condemned to certain death as a deep cover agent.

But his new mission reveals an unlikely ally with one shared goal: the death of David’s greatest enemy.

A brilliant assassination plot is already underway. And the final element is trapped amid the firestorm of a civil war in Myanmar.

To kill his opponent and free his only surviving teammate, David will have to survive impossible odds—odds that he’s determined to beat, no matter the cost.

As a perilous journey unfolds, David learns that appearances aren’t as they seem, and no loyalties are absolute.

He finds himself forced to choose between two great evils—with his only friend’s life hanging in the balance.

David Rivers wanted to lead his team in war. What he got was a suicide mission...

David Rivers is no ordinary mercenary.

He’s just been assigned command of a team in the international criminal war raging in South America.

But the Triple Frontier region is deadly. Narcos and terrorists rule its remote jungle, and David must lead his team into the heart of danger.

Getting in is easy. Getting out might be impossible.

When a high-risk recon mission turns deadly, David’s team must fight for survival against overwhelming odds. Desperate and on the run, they use everything at their disposal just to stay alive.

But getting out will require something more… and if David doesn’t discover the truth behind his current mission, it will be his last.

A war has been raging. Russia is the final battleground. David Rivers will be the first in.

From the city streets of the US to the war-torn deserts of Africa. From the snow-capped mountains of Asia to the narco-controlled jungles of South America, forces have been fighting for control of the ultimate criminal empire.

When an act of violence plunges the contenders into a final confrontation, David Rivers is sent in. He’s the first operative of a mercenary army.

Parachuting into Russia to link up with a mysterious intelligence agent, he must find a way to strike the heart of a ruthless criminal alliance.

The stakes couldn’t be higher. If David doesn’t succeed, he won’t just lose his life—he’ll lose everyone he cares about, too.

Because when this war is over, either one organization will stand…or none of them will.

When a helicopter from an elite special operations unit is shot down, the pilot has only one hope: a covert team of CIA assassins.

It wasn’t supposed to be a rescue mission.

David Rivers and his team were sent to Jolo Island in the Philippines for one reason: to kill a brutal terrorist leader.

But when their target shoots down a US Army helicopter, David and his men must race to rescue the evading pilot before it’s too late.

Because now the enemy knows the Americans are on the island…and he wants to make sure they die there.

While on a covert mission in Syria, CIA special operator David Rivers has just discovered the enemy’s newest target…his own family.

David Rivers is an elite-level assassin. A veteran operator who has served as a Ranger, a mercenary, and now as a CIA contractor conducting covert action around the world.

In his secluded mountain home in Virginia, however, David Rivers lives the quiet life of a family man. His cover legend is so strong that even his wife doesn’t know the true nature of his work.

Half a world away, on a mission to assassinate a foreign operative, Rivers uncovers intelligence pointing to an imminent attack on US soil. Now he must hunt down the terrorists before it’s too late.

But there was something impossibly chilling about this particular intel.

The target is in his hometown...

...and David Rivers’ wife and daughter are mentioned by name.

After the largest terrorist attack in US history is narrowly foiled, the sole enemy survivor has only one name to provide his interrogators: Ghulam Samedi, a fugitive hiding in the rugged mountains of China’s Xinjiang Province.

As part of the CIA’s newly-minted targeted killing program, David Rivers and his team are tasked with assassinating Samedi.

But once they are inside China, there will be no backup, no air support, and no escape—only a handful of local assets with dubious motivations. The location is known for its opium smugglers, violent separatist movement, and heavy deployment of Chinese secret police.

Which is exactly why Rivers’ team of former mercenaries was assembled for this covert operation. They are unilateral, unattributable, and if things go wrong, utterly expendable.

As Rivers embarks on his most challenging mission yet, he will stop at nothing to hunt down Samedi…the last target standing between him and a sinister conspiracy with global implications.

When American citizens in Nigeria are kidnapped and held for ransom, David Rivers and his team of CIA contractors find themselves enveloped in an international firestorm. With a US administration determined to protect American lives, David has the authority to do whatever it takes.

But as David’s team tracks down the mysterious terror cell responsible for the kidnapping, they uncover a conspiracy beyond anything they could have imagined.

And in a race against time to recover the hostages, David and his team must infiltrate the Sambisa Forest, a sprawling Boko Haram stronghold overflowing with enemy soldiers.

Failure is not an option.

Survival is not guaranteed.

David Rivers chases an elusive narco-assassin through the jungles of Colombia in this explosive assassination thriller…

Former FARC revolutionary Sofia Lozano has become the world’s most cunning assassin, and now she’s selling her services to the highest bidder. But when the CIA learns that Sofia’s newest client is an international terrorist syndicate with plans to kill countless civilians, her name is placed on David Rivers’ kill list.

As David and his team track the elusive operative from Colombia’s triple canopy jungles to its Pacific mangrove swamps, his team stumbles onto a larger conspiracy: a narco-sub loaded with cocaine and evidence of a terrorist attack-in-progress.

Faced with a lethal web of drug trafficking, terrorism, and political corruption, David and team must eliminate Sofia before she can complete her deadly plan. And a single mistake could cost them thousands of lives…

David Rivers is used to his targets being chosen by the CIA.

But this time, the target has chosen him.

When a senator’s daughter is kidnapped in Benghazi, a Filipino terrorist named Khalil Noureddin claims responsibility and demands to negotiate with only one man: the leader of a CIA team that tried and failed to kill him over a year ago.

David remembers the failure all too clearly. And while his team narrowly escaped a ruthless terrorist force, the attempt catapulted Khalil into international notoriety and caused him to vanish completely—until now.

With David surrendering himself to Khalil to facilitate hostage negotiations, and his team embarking on a harrowing infiltration across Libya to support the rescue effort, the clock is ticking with an innocent woman’s life hanging in the balance.

But capturing a high-profile hostage is just one element of Khalil’s plan.

To uncover a far more insidious plot unfolding in Libya, David’s team will have to negotiate brutal militias, Russian mercenaries, and operatives of a mysterious terrorist syndicate…before it’s too late.

As an FBI agent, she specialized in hunting America’s most elite thieves. Now, she’s become one of them.

Blair Morgan’s world is in shambles.

After being used as a scapegoat by a corrupt former boss, she is unceremoniously fired from the FBI. Now, with her reputation, pride, and years of service stripped away, Blair just wants to start over.

But when a chance date turns into a mysterious job offer, her past comes crashing back to haunt her.

In a flash, Blair becomes entangled in a high stakes bank heist. Her status as a former FBI-agent-turned-hostage transforms her into an instant media sensation. And the unwanted attention makes her a target for ruthless killers that will stop at nothing to silence her.

Caught in the crosshairs, Blair must confront her past before she loses her freedom—or her life.

But there is something strange about this team of bank robbers. They aren’t who they seem. And as a deadly SWAT raid closes in, Blair discovers that she may not be either...

For former FBI-agent-turned-thief Blair Morgan, the world’s most unbreakable vault is her most irresistible target.

Blair Morgan has embraced her second career—as an elite thief.

Her heist crew has set their sights on their latest target: the Sierra Diamond, an 872-carat stone worth $27.3 million. It will be encased in a new vault known as the Sky Safe, a revolutionary strong room built into the side of a Los Angeles high rise.

The FBI says the Sky Safe is impenetrable. Naturally, Blair and her crew think otherwise…and if they succeed, it will be the greatest heist ever pulled.

But Blair’s corrupt former boss at the FBI has other plans. He knows Blair will be coming for the diamond and intends to catch her in the act…along with her entire team.

As a dangerous game of cat-and-mouse unfolds over the streets of downtown LA, Blair must go head-to-head against the most cunning adversary from her past—or see herself and her crew imprisoned forever.

Before she was a thief, Blair Morgan was a disgraced FBI agent…her corrupt former boss sending her to jail as a scapegoat.

Now a world-class thief, it’s time for Blair’s revenge.

Blair has all the evidence she needs to take her old boss down...she just needs to steal it first.

But when another master thief beats her to the punch, Blair finds her evidence up for sale in a bidding war between her crew, her enemy, and a mysterious figure known only as Fixer. The journey will take her crew from their LA hideout to Washington DC and Manhattan, where the final victor will be determined once and for all.

With ten days until the auction, Blair’s crew must find a way to uncover Fixer’s identity and convince him to join their cause.

If they can’t get leverage, the man who put Blair in jail goes free forever…

...and then he’ll be the one coming after her.

They’ve broken into safes and out of prison, but their greatest heist may be their last.

The Sky Thieves have conquered their worst enemy. Now they face an even greater threat: the ruthless mentor who brought him to power. Uncovering the mentor’s identity is their first step to staying out of jail and exercising their own personal brand of justice—by stealing from the mentor's incalculable wealth.

But they aren’t the only ones looking for clues, as their new opponent activates a vast web of connections to hunt them down. The game is rigged against the Sky Thieves—until a last-minute partnership with an unlikely ally gives them the key to their enemy’s most valuable assets.

In the race to free themselves from a powerful opponent, the crew must undertake their most daunting heist yet...with their lives hanging in the balance.
