In a small town, a young man wakes up to find a different person staring back in the mirror. His skin, once white, has darkened overnight to a 'deep and undeniable brown' and he no longer recognises himself.

At first it seems a unique event, a solitary and individual metamorphosis. But slowly, news spreads: one case becomes several; several becomes many.

And, faced with the prospect of change, society becomes uncertain and fractures.

In the Drawing Room, the award-winning author Mohsin Hamid discusses his new novel, The Last White Man, and how reality forms and changes.
