‘A propulsive, utterly engrossing history.’ —New York Times

‘By profiling the daring pioneers of sleep science, this fascinating, magisterially researched, and brilliantly written book pulls back the covers on one of the great mysteries of being human: why we spend a full third of our lives engaged in an activity that scientists are only beginning to understand. You'll never think about something you do every night the same way again.’ —Steve Silberman, author of Neurotribes
