This book is about a boy named Peter who is 11 or 12 and his little brother Fudge (his real name is Farley Drexel). Their family goes to Maine for 3 weeks and so does their neighbor Sheila!! They end up sharing a house. Fudge (age 5) plans to marry Sheila (age 11) but instead their widowed/widowered grandparents marry each other.
I liked this book because it was funny -- Mrs. A thought Uncle Feather was a bird.
