The world was upside-down. The wind was fire. The sky was ash. The rain was rock.

A couple of hundred years ago, on a quiet Indonesian island, a volcano called Tambora erupted with a force and violence that changed history.

It tore apart the island, and in the months and years that followed, its fallout tore apart the world. The sun refused to shine; the rain refused to stop. Everything that everyone assumed would always be there—a world that made sense, a climate that made sense—was suddenly gone.

From this riot of thunder and lightning, a young woman named Mary Shelley conceived of a scientist and his cursed creature. From the nightmare of Tambora, she wrote a nightmare of a book: Frankenstein—a terrifying reminder of how much damage we humans might do, without even realizing it.

This is the story of a volcano that changed the world and a creature that changed us.

Once upon a time, everything was different. And no one knew if it would ever be the same.

In this masterful work, Nicholas Day, author of the Sibert Award–winning The Mona Lisa Vanishes, brings us a story taken from the archives but seemingly scripted for us today: a tale of climate change and human folly and hope—and what happens when the world suddenly goes wrong.
