"I don't want to sleep " Samuel Hunt proclaims to his mother each night before bedtime. Samuel, like so many children, does not like to sleep. He would rather stay awake and imagine his life as a superhero-and heroes don't sleep, they save the day. That is until one night, when Samuel drifts into reluctant sleep and finds himself in the World of Dreams. Here, he learns of the power of sleep from several unlikely sources. The next morning, when Samuel awakes in his bed, he is armed with the knowledge that sleep is not a punishment, but rather a way to recharge your Sleeper Powers. This allows Samuel to become a Sleeptime Hero: faster, smarter, healthier and taller.
