Set in England in a few years' time, it explores how the meshing of corporate interests, current technology and the lust for power can result in totalitarianism by stealth.

The title of the book made me recall the quote from Sir Edward Grey, the British Foreign Secretary, the day before Britain declared war on Germany in August 1914: "The lamps are going out all over Europe; we shall not see them lit again in our lifetime".
The Dying Light is a thought-provoking novel that shows how a country's democratically-elected government can go so very wrong and stomp on its citizens' entitlements. We've seen it before through history and there's no reason to think it won't happen again.
