"Chris is an astronaut. A very busy astronaut. Saving the planet from aliens is much more important than taking baths or going to bed, because in the darkness that comes before sleep, the worst sorts of aliens appear. These aliens plague Chris -- and his dog -- every night at bedtime. But when Chris watches the first televised lunar landing, he realizes that there's a dark out in space that's much darker than what he's used to, the darkest dark ever, and he discovers that the unknown can be ... exciting! A debut picture book by Commander Chris Hadfield with spectacular illustrations by a brilliant new illustration team, The Fan Brothers, The Darkest Dark is an inspiring story about facing your fears and following your dreams."-- Provided by publisher.
