Davey and the Mech, was inspired by artwork created by artist Caleb Havertape. Caleb's imaginative portrayal of David and Goliath set in the future, played out in Brock's mind and the story around it formed. Firmly rooted in elements of 1 Samuel 17, the story is set into Brock's Quest for Truth galaxy and gives more depth to the larger story playing out in and prior to the events of the Quest for Truth . David and Goliath is Brock's favorite Bible story and was also the focus of his story Showdown with the Shepherd , which was book #5 in the Imagination Station series.
