Detailed book overview



In the near future, advances in medicine and quantum computing make human cloning a reality. For the wealthy, cheating death is the ultimate luxury. To anticloning militants, it’s an abomination against nature. For young Constance “Con” D’Arcy, who was gifted her own clone by her late aunt, it’s terrifying.

After a routine monthly upload of her consciousness―stored for that inevitable transition―something goes wrong. When Con wakes up in the clinic, it’s eighteen months later. Her recent memories are missing. Her original, she’s told, is dead. If that’s true, what does that make her?

The secrets of Con’s disorienting new life are buried deep. So are those of how and why she died. To uncover the truth, Con is retracing the last days she can recall, crossing paths with a detective who’s just as curious. On the run, she needs someone she can trust. Because only one thing has become clear: Con is being marked for murder―all over again.

Cloning is a luxury for the wealthy. For Chance Harker, it’s a way of getting on with his lives. Five years ago, when he was sixteen, he and his brother, Marley, were murdered in a kidnapping gone wrong. Chance was revived—and his grieving parents met his existence with anger, neglect, and aversion. The public, though? They can’t get enough of the death-defying stunts he has parlayed into a social media spectacle.

But after Chance’s latest “refresh,” he awakens to accusations that he’s killed Lee Conway, a stranger Chance has never met. Has one of his clones? With no memory of his previous selves, and working fast before he’s arrested, Chance digs into Conway’s background, the mysteries of his own life—and death—and the tragic abduction that tore his family apart.

All Chance has to do is stay ahead of the LAPD; his kidnappers, who are back on the hunt; and a growing mob of incensed protesters outraged that a rich clone appears to be getting away with murder.

Gibson Vaughn

The Short Drop

A decade ago, fourteen-year-old Suzanne Lombard, the daughter of Benjamin Lombard―then a senator, now a powerful vice president running for the presidency―disappeared in the most sensational missing-person case in the nation’s history. Still unsolved, the mystery remains a national obsession.

For legendary hacker and marine Gibson Vaughn, the case is personal―Suzanne Lombard had been like a sister to him. On the tenth anniversary of her disappearance, the former head of Benjamin Lombard’s security asks for Gibson’s help in a covert investigation of the case, with new evidence in hand.

Haunted by tragic memories, he jumps at the chance to uncover what happened all those years ago. Using his military and technical prowess, he soon discovers multiple conspiracies surrounding the Lombard family―and he encounters powerful, ruthless political players who will do anything to silence him and his team. 

With new information surfacing that could threaten Lombard’s bid for the presidency, Gibson must stay one step ahead as he navigates a dangerous web to get to the truth.

Poison Feather

When jailed billionaire Charles Merrick hints publicly that he has stashed a fortune in an offshore cache, a school of sharks converges upon his release from federal prison.

Among his swindled victims is Judge Hammond Birk, the man who saved Gibson Vaughn’s life when he was a troubled teenager. Now Gibson intends to repay that debt by recovering Merrick’s victims’ money.

But Gibson isn’t the only one on the trail of the hidden fortune.

The promise of billions has drawn a horde of ruthless treasure hunters, including an edgy ex-con, a female bartender with a mysterious history, a Chinese spy with a passion for fly-fishing, and a veritable army of hardened mercenaries. 

To stay ahead of the sharks and win justice for his mentor, Gibson will need all his formidable skills. But at the end of the road, he’ll still have to face “Poisonfeather”―a geopolitical secret that just might get Gibson killed…or worse.

Debris Line

Lying low on the sun-kissed coast of Portugal is a far cry from twenty-four-hour lockdown in a CIA black-site prison. But even in paradise, Gibson Vaughn is a long way from being home free. With the feds hot on his heels, he and his crew of fellow fugitives know they can’t hide in a sunny beach town forever. And before they go on the run again, their generous host―a wealthy drug smuggler―expects to be paid for his hospitality. And paid double.

His price? A nearly impossible operation that Gibson and his gang must pull off to retrieve a king’s ransom in hijacked narcotics. Even if they make it out alive, they’ll have to face the wrath of a ruthless Mexican cartel that plays dirty…and is used to winning. But when Gibson discovers there’s far more than drugs at stake, the heist becomes a daring mission of rescue and mercy―and righteous vengeance.

Origami Man

Former Marine, brilliant hacker, and wanted fugitive Gibson Vaughn is off the grid in the Caymans. Until the ice-cold assassin Tinsley draws him out of the shadows. Complying with the man who murdered his father and left Gibson for dead? In the war against terror, never say never.

Especially when half a million lives are at stake.

Tinsley’s in possession of a heavily encrypted thumb drive. But the details of the plot―the motive, the targets, and the day of execution―are a mystery. The one certainty is that a tenuous truce must be made. After joining forces with Tinsley, Gibson and his team have their mission: access the drive and abort a massacre in the making.

How far can Gibson really trust Tinsley? Time will tell. Right now they’re both running out of it as they race across Europe to find an elusive cyber-psycho behind the mother of all malware.

Whoever said to keep your friends close but your enemies closer never meant it like this.
