The Darkest Dark by astronaut Chris Hadfield illustrated by The Fan Brothers*

Chris loves space and dreams of being astronaut.  He, however, is afraid of the dark which he discovers one night when he watches a televised showing of  Neil Armstrong on the moon will be a huge problem!  "Space was the darkest dark ever."
This book explores fear in a honest way and offers hope to anyone's whose fears may interfere with his/her dreams.
The Fan Brothers' illustrations are superb (We love their book The Night Gardener.  We own it.).
*Highly recommend.
