From the award-winning creators of Your Fantastic Elastic Brain comes a new adventure into the science of how the brain works at night, and the importance of sleep!

When you go to sleep, what does your brain do? Does it rest too? No—it's busy working while you snooze! It repairs, and resets, and helps your body even when you're not awake.

Using up-to-date research to explore our brains' critical functions when we are asleep, psychology experts JoAnn and Terrence Deak invite kids (and adults) to unpack all the amazing things your brain is doing when you're not awake—and why it's so important to get your sleep!
