This funny and factual picture book from Heart and Brain creator Nick Seluk explains the science behind everything the brain helps you do: keeping your heart beating, telling you when you are sleepy, remembering stuff, and more. The brain is in charge of everything you do, every minute of every day for your entire life. That's kind of a big deal.
