Investigator Sloan McPherson finds a frightened vagrant suffering from amnesia living in a Florida swamp—then learns he disappeared from Oregon when he was a teenager. To find out how he ended up three thousand miles from home thirty years later, Sloan enlists the help of two brilliant colleagues. FBI agent Jessica Blackwood and scientist Theo Cray have already made an alarming connection. A female classmate of the Everglades drifter disappeared at the same time, and their high school journals reveal ties to an enigmatic figure they both called Mr. Whisper.

A train derails in Idaho, nearly causing a nuclear disaster. An inferno at a battery facility in Florida disrupts the electrical grid for days. A potentially devastating failure is discovered at Virginia’s Mud River Dam. To computational biologist Theo Cray, these aren’t mere infrastructure accidents. They are virtually undetectable acts of sabotage. Theo sees a mathematical pattern to the madness that few others can comprehend—except for his associates: rogue FBI agent Jessica Blackwood, private security specialist Brad Trasker, and Florida underwater investigator Sloan McPherson.

Sloan McPherson and the Underwater Investigation Unit have discovered a van at the bottom of a murky Florida pond. Sealed inside the watery tomb are the bodies of four teenagers who disappeared 30 years ago after leaving a rock concert. To authorities, it looks like a tragic accident. To Sloan, it looks like murder. Every piece of evidence is starting to connect to a string of cold case vanishings throughout Florida. Clue by clue, Sloan navigates the warm, dark waters where natural predators feed, knowing that the most dangerous one is still above the surface - nesting and dormant.

The FBI calls on former agent Jessica Blackwood to look at a puzzling crime. A wildlife officer has found the body of a popular YouTuber encased in an obelisk made of salt in a remote refuge. When the agency is tipped off to a second body, that of a TikTok star chained to the bottom of Nevada’s Pyramid Lake—her hands clasped in prayer—Jessica recruits a trusted colleague of her own: Floridian underwater investigator Sloan McPherson.

Professor Theo Cray is trained to see patterns where others see chaos. So when mutilated bodies found deep in the Montana woods leave the cops searching blindly for clues, Theo sees something they missed. Something unnatural. Something only he can stop. As a computational biologist, Theo is more familiar with digital code and microbes than the dark arts of forensic sleuthing.

After the Underwater Investigation Unit’s disbandment, public outcry ushers Sloan McPherson and her partner, former navy diver Scott Hughes, back into the depths of crime solving. But Sloan’s return comes with a personal case. Longtime family friend Fred Stafford has disappeared. Left behind: his abandoned truck in the vicinity of an unmarked sinkhole and new findings that have Sloan second-guessing everything she thought she knew about the man.

When a young woman washes ashore on a Fort Lauderdale beach, Sloan McPherson of the Underwater Investigation Unit is called in to consult. Sloan’s instinct says murder, but even then, there are too many questions. For answers she reaches out to Gwen Wylder. The Miami homicide detective is notorious for being manipulative, bitter, a tyrant to her peers, and wicked smart. And she demands something in return from Sloan: fresh insight into seemingly unrelated cold-case murders and disappearances—and a possible serial killer trolling the Florida coast.

After three decades in counterintelligence, Brad Trasker is retired, disillusioned, and dealing with a tragic loss. Spy games are behind him until he attends the launch of a next-generation aircraft. When the project of innovative aerospace CEO Kylie Connor explodes on the tarmac—nearly killing her in the process—Trasker is pulled back into the line of fire. The mystery of the sabotage quickly deepens.

Computational biologist and serial-killer hunter Dr. Theo Cray receives an off-the-record request from the FBI to investigate an inexplicable double homicide. It happened at the excavation site where a murderer had buried his victims’ remains. In custody is a forensic technician in shock, with no history of aggression. He doesn’t remember a thing. His colleagues don’t even recognize the man they thought they knew. But an MRI reveals something peculiar. And abnormal.

A signal is detected at the outer edge of the solar system. Computational biologist Dr. Theo Cray and magician-turned-FBI-agent Jessica Blackwood are looking—and listening—a little closer. The man at the center of this cosmic mystery is billionaire Thomas T. Theismann. He’s spent a lifetime—and a fortune—trying to find out if we’re alone in the universe. Highly skeptical, Theo joins the effort to find the source of the signal, and he quickly enlists Jessica to look into the suspicious death of another academic at the lab.

Professor Theo Cray caught one of the most prolific serial killers in history using revolutionary scientific methods. Cut off from university research because of the shroud of suspicion around him after the death of his former student and the aftermath of catching his quarry, Cray tries to rebuild his life but finds himself drawn into another unsolved case. The desperate father of a missing child, ignored by the authorities and abandoned by his community, turns to Theo for help.

A mysterious electrical storm plunges Manhattan into darkness. As a strange, smothering fog rolls in, all communication crashes. In the blink of an eye, the island seems to vanish into a void. FBI special agent Jessica Blackwood and brilliant scientist Dr. Theo Cray know this isn’t a freak accident. It’s a sinister sleight of hand. Their greatest adversary, a serial killer and cultist known as the Warlock, has escaped during a prison transfer in New York. A depraved master of manipulation, he promised the end of days. He’s making good on it.

A distress call draws rescuers Sloan McPherson and the Underwater Investigation Unit to a cruise ship off the coast of Fort Lauderdale that’s sinking from a mysterious explosion. When it appears to be the work of an ecoterrorist and other ships are threatened, it becomes a race against time. More clues are discovered, and evidence is in danger of being washed away by a coming tropical storm. Sloan grows concerned that key details are being ignored, and a strange lack of urgency by authorities sets off alarms.

Dr. Theo Cray has a legendary mathematical knack for catching serial killers. Until his exposure to a mind-altering pathogen knocks him off his game. It has upended an investigation, destroyed his reputation, and left him to question his own sanity. One person still trusts him to finish the job. His former professor Amanda Paulson is helping point Cray down a logical path to his prey: a nomadic health-care worker whose murder spree stretches back decades and whose victims number in the hundreds.

Coming from scandalous Florida treasure hunters and drug smugglers, Sloan McPherson is forging her own path, for herself and for her daughter, out from under her family’s shadow. An auxiliary officer for Lauderdale Shores PD, she’s the go-to diver for evidence recovery. Then Sloan finds a fresh kill floating in a canal - a woman whose murky history collides with Sloan’s. Their troubling ties are making Sloan less a potential witness than a suspect. And her colleagues aren’t the only ones following every move she makes. So is the killer.

Retired intelligence operative Brad Trasker heads security at a remote aerospace facility when there’s a major breach. A photo of their top-secret AI-designed hydrogen engine has surfaced online. Trasker’s investigation into who did it soon leads to a start-up in Bangkok, where its three software developers have disappeared, along with nearly a million dollars in investment money. Following their tracks, Trasker hits a dead end. The start-up’s HQ is a padlocked crime scene.

Wall Street Journal bestselling novelist and former OpenAI science communicator Andrew Mayne pulls back the curtain on how human imagination and artificial intelligence fuse to shape tomorrow’s breakthroughs.
