'A Horse Called Hero' is an excellent book about courage, trust, and love. This book is descriptively written and excellently constructed. (In Great Britain during the WWII years, the novel gave me a feeling of nostalgia.) Well-constructed plot, realistic characterization, and centralized conflict — these all are built upon each other to create this heartwarming story. The superbly crafted ending made me leave the story a bit emotional (I had to read the ending three times!) but very satisfied. As for the theme of the book goes, it can be summed up in the words of C. S. Lewis included at the beginning of the book: "Courage is not simply one of the virtues, but the form of every virtue at its testing point."
