This entertaining story carries on where the other books left off. It is mostly his account of his experiences in the RAF during WWII. Many things that happen to him during basic training and learning to be a pilot remind him of his experiences as a county vet, so we get a double set of memories.
Each chapter tells a bit of his experience during training and a look back at some memorable animal or character, all entertaining. If you liked Herriot’s other books, this will appeal to you as well.
