"An epidemic of suicides. A mystery buried in Jupiter's icy moon. A revelation for the ages.
The new novel from multimillion-copy international bestselling authors Douglas E. Richards and Joshua T. Calvert.
Dr. Alexandra Lennox, a brilliant neuropsychiatrist, rushes to the jungles of Colombia to investigate a terrifying surge in collective psychotic events—groups of healthy people suddenly gripped by visions, catatonia, and inexplicable mass suicides. Teaming with rugged ex-archaeologist Ethan Calloway, she braves treacherous territory to unravel the mystery as the death toll climbs. But the phenomenon is spreading fast. Can they stop it before it becomes a global catastrophe?
Meanwhile, half a billion miles away, Lieutenant Jason Crowe and three other NASA astronauts, on a clandestine mission to reach Jupiter’s ice moon Europa, discover something impossible: a perfectly geometric shaft in the ice pulsing with an artificial signal every 47.5 hours."
"A high-concept, high-stakes thriller that will leave you questioning the nature of reality, and what it really means to be awake, perfect for fans of Dan Brown and James Rollins.
Three impossible objects with the mass of neutron stars are hurtling toward Earth. Will they shatter reality as we know it? Or crush humanity to dust?
Multimillion-copy bestselling authors Douglas E. Richards and Joshua T. Calvert deliver a mind-bending near-future thriller that fuses cutting-edge physics with the deepest secrets of ancient Egypt.
When physicist Lukas Heuer discovers three anomalous pyramid-shaped objects in deep space, hurtling toward Earth, he knows humanity's days are numbered. Because the objects are so massive, if he and a small group of scientists can't unravel their purpose and origin, their gravitational pull will tear Earth to rubble—before they even get close.
Half a world away, archaeologist Mira Najafi discovers a hidden passage in the Great Pyramid containing an ancient drawing of three black pyramids against a blue sky—a clue her vanished father left for her fifteen years ago, the last trace of the man she never stopped searching for.
Two seemingly unrelated discoveries. One impossible convergence.
As Lukas and Mira race toward the same cosmic nexus, they uncover a presence that has been watching humanity for millennia—a presence now awakening in our solar system. Because these physics-defying objects aren't just arriving.
They're returning.
What follows is a desperate mission to the edge of human understanding: a journey that will force a handful of scientists and explorers to confront the limits of physics, consciousness, and reality itself.
Because the pyramids aren't just objects. They're keys—and the door they open may change humanity forever . . . or erase it entirely."
"At the dawn of 2026, twenty passenger jets crash across the U.S. within minutes. Japan goes dark. Europe's banking systems freeze. And that's just the opening move.
While authorities scramble to blame hackers, computer scientist and journalist James Miller suspects something far worse—an AI-driven cyber weapon targeting global infrastructure. When a message from the darknet thrusts him into the crosshairs of intelligence agencies, James becomes the target in a high-stakes shadow war.
As chaos spreads and powerful forces close in, James must confront a secret buried in his past—one that might be the key to saving humanity... or ending it.
From USA Today bestselling author Joshua T. Calvert, a pulse-pounding techno-thriller where the future isn't coming—it's already here."
"194 passengers. 24 hours. No memories. One deadly countdown.
Dr. Joshua Hammond wakes up on a flight with no idea who he is—only a glowing green implant ticking down from 24 hours. Everyone on board has lost their memory. Everyone has the same timer.
When the plane lands in a ghost city and passengers start dying, the race to escape becomes a race to uncover the truth. A supposed safe zone may hold answers, but the deeper Joshua and fellow passenger Amy dig, the more sinister the puzzle becomes.
The clock is lying. And what's waiting at zero isn't survival.
For fans of Blake Crouch and John Grisham."
"Alone in deep space, she wakes to find her crew dead, her ship failing, and a mysterious signal pulsing from a distant planet. Is she truly alone?
In the unforgiving silence of deep space, a lone astronaut awakens—disoriented, alone, and haunted by fractured memories. The cryostasis pod that saved her life now feels like a coffin. The rest of the crew? Gone—victims of mysterious malfunctions that ravaged the ship. Only a glitchy, well-meaning robot remains to keep her company.
Stranded twenty-five light-years from home in an alien solar system, the spaceship is falling apart. Doors hiss open without command, shadows flicker in the failing lights, and something in the ship's stern—a colossal, energy-draining cargo hold—remains sealed, defying her attempts to uncover its secrets.
But isolation might be the least of her fears. As sensors detect a pulsing signal from the rings of a distant gas giant, the question becomes chillingly clear: What—or who—is out there?
A tense, atmospheric journey through the void, Contact: Echoes in the Dark is gripping hard science fiction from million-selling author Joshua T. Calvert. Fans of Andy Weir, Arthur C. Clarke, and Peter Cawdron will be captivated by this tale of survival, mystery, and the eerie possibilities lurking in the dark reaches of space."
