The book that inpsired my parents

There wasn't really a book that inspired them but I remember my mother telling me about a fascinating book she read, it was called Animal Farm, a book we were about to discuss later in the year.
She told me that Animal Farm was indeed an interesting book and she was studying it when she was a student. She said that the school had used the book as an literature piece and they were supposed to study it.
Later, the teacher would then test them on the things in the book, it is similar to what we are doing now.
