"A tour-de-force for our times . . . At once a heart-stopping tale of climate change and a profoundly hopeful call to action."--Katherine Applegate, Newbery Medal winner for The One and Only Ivan

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.
