"The Probyn boys, Adolphus and Constantine are going to live with a tutor and his family. The family consists of Mr. and Mrs. Roby, and their children, Aleck, Bertha and Laura. The Probyns are thoughtless, selfish, rude and spoiled. The Roby children are quick to react and point out the faults of the Probyns, but their mother is more concerned with them seeing their own faults and overcoming them. The story jumps back and forth between the adventures and struggles of the children, to the allegory of "The Giant Killer" which their mother reads to them...inspires all of us to deal with the Giants in our hearts, while having grace for the faults of others"--from Back cover.
