Threshold Zero (en Inglés) - Davis Shyaka Musirikare

It starts with a silence so deep it stops the human heart.

At midnight, in cities across the globe, the world holds its breath. For sixty seconds, all sound vanishes. Electronics freeze. The hum of civilization dies. And in that terrifying quiet, a visitor arrives.

He is a child in a yellow raincoat. He knocks once. If you open the door, he offers you a gift-and a burden.

In Nairobi, signal analyst Zola Mbeki captures a frequency that shouldn't exist-a broadcast from the end of the world. In Tokyo, exhausted architect Kenji Sato receives a rusted key that can open any lock, physical or metaphysical. In Sao Paulo, arrogant neurosurgeon Dr. Mateo Silva is branded by a void energy that defies medical science. In London, paramedic Maya Al-Fayed gains the Sight, revealing the terrifying, violet infrastructure overlaying our reality.

They are strangers separated by continents, but bound by a single, terrifying truth: Earth is being evicted.

Ancient, extra-dimensional entities known as "The Landlords" have returned to harvest the complexity of human history. Aided by a rogue AI defense program named Vector Black, they are preparing to format the planet. The violet sky is their bruising; the silence is their shadow.

Hunted by synthetic soldiers and haunted by the ghosts of a dying internet, Zola, Kenji, Mateo, and Maya must race to the bottom of the world. In the frozen wastes of Antarctica, a forgotten station holds the only switch that can stop the harvest-a "Needle" that promises a factory reset of the human race.

But to save humanity, they might have to erase it.

Threshold Zero is a high-octane global thriller that spans from the neon rain of Tokyo to the silent ice of the South Pole. It is a story about the cost of survival, the weight of memory, and the courage it takes to knock back when the darkness comes calling.
