The Great Godden: Meg Rosoff

This is the story of one family, one dreamy summer - the summer when everything changes. In a holiday house by the sea, in a big, messy family, one teenager watches as brothers and sisters, parents and older cousins fill hot days with wine and games and planning a wedding.
Enter the Goddens - irresistible, charming, languidly sexy Kit and surly, silent Hugo. Suddenly there's a serpent in this paradise - and the consequences will be devastating.
From bestselling, award-winning author Meg Rosoff comes a lyrical and quintessential coming-of-age tale - a summer book that's as heady, timeless and irresistible as Bonjour Tristesse and I Capture the Castle but as sharp and fresh as Normal People.
