One day, Petunia, the silly goose, finds a book lying on the ground. Petunia has heard the farmer say that those who own books and love them will be wise, so she keeps the book, believing that she will no longer be a silly goose. With her new-found wisdom, Petunia feels that she is qualified to give advice to the rest of the farm animals but, since she has never read the book, her advice has disastrous (and explosive) results.
Petunia is a silly story with a moral. Although the moral is a little too obvious, the rest of the book comes across well, is very enjoyable, and makes a good start to a small series featuring the silly goose.
