Synopsis for Gradient Descent

Save the dog, save the Earth, save the future!Physicist Minerva Draper and engineer Maxine Cantros love their work and hate their jobs. They hone the most destructive force in the Universe to create new technologies, at a company rotten with corporate lackeys, where profit trumps people and the budget doesn’t cover public safety.

When they run an experiment to save their beloved dog, a cataclysm erupts. The Earth is in peril, and middle management pins the blame square on the women.

To survive, they must outsmart murder-craving geniuses. Defend against weapons from the future. And destroy institutional misogyny. To save the future, they must grok how an impossible technology has destroyed the world.

But first, they need to rescue a dog that’s already dead.

Min and Max broke physics to save their dog; now humanity is doomed.
