The Darkest Dark by Chris Hadfield (2016)
Chris loves rockets and planets and pretending he's a brave astronaut, exploring the universe. Only one problem--at night, Chris doesn't feel so brave. He's afraid of the dark. But when he watches the groundbreaking moon landing on TV, he realizes that space is the darkest dark there is--and the dark is beautiful and exciting, especially when you have big dreams to keep you company.
