When George is kept awake in the middle of the night by toothache, she notices a light on the supposedly empty Kirrin Island. While George is at the dentist, Julian, Dick and Anne decide to investigate and strange things start happening...

Can the Famous Five solve this mystery?

In addition to the 21 novels in the Famous Five series, Enid Blyton wrote a clutch of short stories based on the characters. These were published in magazines and were collected in the Famous Five Short Story Collection (Hodder). For the first time, the complete text of Five and a Half-Term Adventure appears in an individual volume, illustrated in full colour.
