When the sun went dark, humanity became the fertilizer.
The sky went wrong on a Tuesday. The blue vanished. 432 nanometers-the wavelength of chlorophyll-erased from the sun. In 20 days, the plants died. In 40 days, 7 billion people followed.
Dr. Aris Sen was supposed to die with them.
He didn't.
Because the vaccine wasn't a cure. It was a seed. Now the sun lives in his blood. Now he's 41.7% human. The rest is something else. Something that photosynthesizes.
The world is dead. The sky is black. The temperature is -91 C.
But under the glass, something green is growing. A tree that walks. A six-year-old girl who eats sunlight. A bear cub with hexagon eyes.
And the aliens who killed the sun? They're finally here.
They don't want to invade. They want to harvest.
Earth is a failed experiment. A photosynthesis test field. And the girl is the only crop worth saving.
The Cold Equation is simple: One life for 8 billion graves.
Aris is a scientist. He knows how the math works.
He's a father. He knows how it doesn't.
To save the last child on Earth, he'll have to cheat the Great Filter. He'll have to turn the weapon that killed the world into a vaccine for the solar system. He'll have to die to broadcast it.
Unless she stops him first.
Weeds is a hard sci-fi alien invasion thriller for fans of Project Hail Mary, Children of Time, and Annihilation.
If you like cosmic horror, biological sci-fi, and first contact where humanity isn't the hero-welcome to the farm.
