The Penderwicks are four sisters, as different as chalk from cheese, yet as close as can be. The eldest, Rosalind, is responsible and practical; Skye, stubborn and feisty; dreamy, artistic, budding novelist, Jane; and shy little Batty, who doesn't go anywhere without her butterfly wings. And not forgetting Hound, their large lumbering lovable dog. The four girls and their absent-minded father head off for their summer holidays, but instead of the cosy tumbledown cottage they expect, they find themselves on a huge estate called Arundel, with magnificent gardens ripe for exploring. It isn't long before they become embroiled in all sorts of scrapes with new-found friend, Jeffrey - but his mother, the icy-hearted Mrs Tifton, must be avoided at all costs. Chaotic adventures ensue, and it soon becomes a summer the sisters will never forget...
