The end of the world happens in the blink of an eye.

When The Snap sweeps the globe, everyone can instantly hear everything that everyone else is thinking. As secrets and lies are laid bare, suburbs and cities explode into insanity and violence.

What might have been an evolutionary leap instead initiates the apocalypse.

Sixteen-year-old Danby Armstrong's telepathy works very differently. She can tune into other people but they can't tune into her. With only this slender defence, Danby must protect her little brother and reach the safety of her mother's mountain retreat.

But it's 100 kilometres away and the highways are blocked by thousands of cars and surrounded by millions of people coming apart at the psychic seams.

Danby's escape is made even more dangerous by another cataclysm that threatens humanity's extinction. And her ability to survive this new world will be tested by a charismatic young man whose power to save lives may be worse than death itself.
