Awakened

""I've been an insomniac all of my life, but I'm not Sleepless and I won't become Sleepless, just as long as the chips that were put into their heads never get put into mine. There's little chance of that, since I won't put the machinery into my brain and neither will Edgar and neither will the Professor, and we're the only three left who could. I don't want to be Sleepless..." Civilisation has ended. In a bid to make us more productive, to give us more time, science took sleep from humanity. But sleeplessness turned people into feral monsters and now a small group of scientists are trapped in the Tower of London, consumed by guilt at what they have done and desperately searching for a cure. And then one day, as the last ravens circle, two miraculous survivors walk into the Tower. Are they the answer or a terrible question?"--
