Summary:
One mistake dooms humanity . . .

When an antigravity experiment goes wrong, humanity is brought to its knees by an unknown and unstoppable force that begins to systematically exterminate all life on Earth.

Grid failures, anarchy, uprisings, and murder are just the start when the planet is thrown into chaos as millions die a horrible, tragic death.

Billions more will perish unless physicist Lucas Ramsay and his brilliant foster brother can devise a plan to stop the extinction of mankind. However, just when they think the nightmare couldn’t get any worse, they soon learn they’ve been maneuvered into the middle of a much larger saga, one where reality is measured on a planetary scale.

Nothing is as it appears to be and the Ramsay brothers don’t know who to trust, challenging their faith in science and each other.
