When a young woman washes ashore on a Fort Lauderdale beach, Sloan McPherson of the Underwater Investigation Unit is called in to consult. 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. As loose ends of the old files begin to come together, another woman disappears. Sloan and Gwen are certain she’s the newest link in a deadly chain. They are determined to track her down before she dies, but they soon find themselves in uncharted waters.

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. As their investigations converge, they uncover curious connections to the otherworldly contact, including a 1970s science-fiction writer and the body of an astronaut found buried in an ancient tomb.

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. As the troubling questions compound, Sloan is determined to chase down every lead she has. Her persistence is getting her closer to the truth: that there’s something far more troubling at play than the official explanation. It’s also putting Sloan on a collision course with an enemy more powerful than she realizes.

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. One by one, cities across the globe are erupting in chaos as they disappear into the same black holes. But the voids are just a warm-up for something bigger.

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. But when a fresh young kill is found in the Everglades, Sloan fears that her investigation has reawakened a monster. How can she catch someone who’s a genius at hiding in plain sight? By acting as prey. The dangerous gambit is working --- only too well. She’s being lured into a deception of the madman’s own design. Has Sloan set a trap for a serial killer? Or has he set one for her?

FBI agent Jessica Blackwood believes she has successfully left her complicated life as a gifted magician behind her...until a killer with seemingly supernatural powers puts her talents to the ultimate test. A mysterious hacker, who identifies himself as “Warlock,” brings down the FBI’s website and posts the GPS coordinates of a Michigan cemetery in its place.  The body in the cemetery is only the first in the Warlock’s series of dark miracles. Thrust into the media spotlight, with time ticking away until the next crime, can Jessica confront her past to embrace her gifts and stop a depraved killer?
