Meridian Collapse

Forty-one hours. That's how long the Meridian Space Elevator has before it tears itself apart and scours a colony world clean. Zak Decker knows this because he built the elevator. He knows the resonance signatures, the load tolerances, the precise mathematics of catastrophic failure. He was the chief structural engineer until a disaster stripped him of everything. His clearance. His reputation. His daughter, Kestrel, who still works forty thousand feet above him on the very station he was banned from. He's spent seven years drinking the memory away in the gutter levels of Meridian City. He's got forty-one hours to climb back up. When impossible resonance patterns ripple through the tether, Decker is the only one who recognizes the signature. This isn't mechanical failure. Someone designed this. An elegant, vicious sabotage sequence built by someone who knows the structure as intimately as he does. And the final pulse will send the orbital platform Kestrel and forty thousand others aboard plummeting through the atmosphere in a debris storm. The security commander who drags Decker back into the crisis despises him. The evacuation timeline is already impossible. Every failsafe has been subverted by the same minds that designed them. And somewhere on the station, someone is actively blocking rescue operations. Then Decker finds the signal. Buried inside the sabotage code itself. A transmission from beyond the system's edge the same pattern that ended his career seven years ago. The same signal that broke his family apart. It's back. And it's using the elevator's own frequencies to speak. As Decker fights his way up the tether through chaos, old enemies, and the suffocating weight of his own past, one question keeps cutting through the noise: why does someone need forty thousand people to die?The answer is buried in the signal. And it changes everything. The Meridian Collapse is a relentless hard science fiction thriller about sacrifice, redemption, first contact, and a father's race to save the daughter he abandoned before the sky falls. Perfect for readers who love Project Hail Mary, Children of Time, space adventure thrillers, first contact stories, countdown narratives, and hard SF with genuine emotional stakes. A relentless, twist-packed standalone thriller.
