The Penderwicks: A Summer Tale of Four Sisters, Two Rabbits, and a Very Interesting Boy by Jeanne Birdsall (kid's book)

I adored this charming, funny little kid's book. It reminds me of a book I used to read over and over when I was growing up - Five Little Peppers and How They Grew -- only a bit more contemporary. Four sisters and their intrepid dog ("Hound") have all sorts of adventures on their summer vacation. I highly recommend this wonderful book.
