A WORLD HALF IN DARKNESS. A SECRET SHE MUST BRING TO LIGHT.

2059. The world has stopped turning.

One half suffers an endless frozen night; the other, nothing but burning sun.

Only in a slim twilit region between them can life survive.

In an isolationist Britain, scientist Ellen Hopper receives a letter from a dying man. It contains a powerful and dangerous secret.

One that those in power will kill to conceal...

THE LAST DAY: an utterly original thriller from an exciting new voice, perfect for readers who loved Robert Harris' Fatherland, Emily St. John Mandel's Station 11, and The Wall by John Lanchester.

'Wonderful: boldly imagined and beautifully written - the best future-shock thriller for years.'
LEE CHILD
