Wanting a fresh perspective on her own life, the writer Helen Gordon set out to read that epic narrative. Her odyssey takes her from the secret fossils of London to the 3-billion-year-old rocks of the Scottish Highlands, and from a state-of-the-art earthquake monitoring system in California to one of the world's most dangerous volcanic complexes, hidden beneath the green hills of Naples. At every step, she finds that the apparently solid ground beneath our feet isn't quite as it seems.
In deep time, Gordon finds, everything is provisional. Bones become rock. Sands become mountains. Oceans become cities. And life goes on.
