The Highest Apple / An Ubhal as Àirde is the first comprehensive anthology of the Gaelic literature of Scotland, from the early Middle Ages to the present day.

It includes more than 200 texts from a wide range of genres of literature, including poems, songs, folktales, medieval romances, short stories, novels, and plays, from different corners of the Gaelic diaspora in addition to Scotland itself. English translations accompany the Scottish Gaelic originals.

The volume also contextualises the position of Gaelic in Scotland across the ages with texts that reflect varying perceptions of the social role and significance of the language.
