Five on a Treasure Island (Knight Books) by Enid Blyton ISBN 13: 9780340024232

"Ah, the Famous Five! In this first book, we open with Julian, Dick and Anne at home with their parents, chatting around the breakfast table. Julian asks his mother if they're going to Polseath as usual for the summer holidays—but to the childrens' surprise their parents have decided they want to go away on their own to Scotland. The children must go to stay with their Aunt Fanny and Uncle Quentin, down by the sea at Kirrin Bay. They have a daughter by the name of Georgina, who is very lonely and could do with the company of a few cousins. And so plans are made, and they all pile into the car and set off."
