Full-Band Blocking of the Earth-Ionosphere Magnetosphere

I am a devoted fan of Liu Cixin. I borrowed some lines and ideas, but the main story is entirely my own conception. This is my first novel, so I hope readers will be understanding.

The geomagnetic shield shatters, communications across all frequencies are blocked, and the world is cut into countless isolated islands. Humanity stakes everything on a space expedition toward the sun, attempting to stop the world-ending disaster coming from it. A tiny butterfly-effect deviation sends this global rescue plan, backed by all of humanity's strength, toward failure. Amid the ruins of the apocalypse and the sealed bunkers, Ye Xiaoting records civilization's choices, despair, and tenderness. At the end of the disaster, she leaves humanity a page of history that will never be erased.
