Summary
"An insomnia pandemic is sweeping the globe, leaving people unable to function and society on the brink of collapse... Dr. Cooper Delaney believes he has the answer: Noctural, a new sleep-aid--one with absolutely no side-effects--which in early testing shows 100% effectiveness. The only problem is, it doesn't work. With no warning. No explanation. Unable to accept the drug's inexplicable failure and unwilling to concede to the competition, lines are crossed, ethical boundaries are pushed to the breaking point, and disturbing realizations come to light that could completely unravel civilization as we know it... and throw into question humanity's place in the universe."--Provided by publisher.
