"As the house cools and warms it makes noises.So, for me it was very well-populated with aliens and monsters and things shifting in the dark."

As a boy, Hadfield was often tasked with cleaning out the horses' stables on his family's farm, a job thatrequired him to face his fear of the dark.

"It was everything I could do to summon my courage to climb up that ladder and pop my head up into that dark hay mow, sure that there was some horrible creature with a scythe there just waiting for me," he told host Alan Neal.

The illustrationsin the book were drawn by artists and brothers Terry and Eric Fan. "I took them to our summer cottage where so much of this story occurred," said Hadfield.

"So they got to see it [and] we talked about the darkness. What they drew, I thinkso elegantly, was the feel of the dark."

Hadfield said he hoped his book will help teachkids how to conquer their own fears. "The whole point of the book of course is, it's OK and normal to be afraid. But what do you do about it?"
