On 26 April 1986 at 1.23am a reactor at the Chernobyl Nuclear Power Plant in Soviet Ukraine exploded. While the authorities scrambled to understand what was occurring, workers, engineers, firefighters and those living in the area were abandoned to their fate. The blast put the world on the brink of nuclear annihilation, contaminating over half of Europe with radioactive fallout. Winner of the Baillie Gifford Nonfiction Prize 2018
