This picture book uses the framework of a day spent in the company of two small children exploring the environment of their Hebridean island to introduce the letters of the alphabet in a series of descriptive phrases. It chooses examples of words marking unique features of the place, its history and culture: thus C is for cotton grass and crofts; H is for haar, and M for machair. The familiarity of the alphabet is the vehicle for an engaging portrait of the diversity of lifestyles - and language - within the British Isles.
