Farm Boy, by Michael Morpurgo, is the sequel to War Horse. I found that it was much shorter than the first book but I still enjoyed it.
Instead of telling the story from Joey's point of view, it is told by Albert's descendants. The book leaves you happily satisfied with Joey's and Albert's life after they return from war.
For years, Joey was a war horse, pulling ambulance carts and artillery through the battlefields of World War I. When he finally returned home to Albert and the farm, he was treated like a hero. But his adventures had only just begun.
Now, generations later, Albert's son loves to tell his own grandson stories about the remarkable horse. He tells him of Joey's feats in the war, and of the time when the family risked everything betting that Joey could win a daring race. As he tells the stories, he slowly reveals a shameful secret--a secret that he's kept to himself for years.
This charming book speaks to the bond between generations, and captures the spirit of rural life and the love of horses.
