Air Cuan Dubh Drilseach (On a Glittering Black Sea) is an award winning science fiction novel written in Scottish Gaelic by Tim Armstrong. Air Cuan Dubh Drilseach is the first hard science-fiction novel in Gaelic written for adults. The story combines elements of space opera, dark cyberpunk, romance and rock-band road-trip adventure. The central conceit of the novel is that in space, everyone speaks Gaelic, allowing the author to create an entirely Gaelic-speaking world for the characters. Air Cuan Dubh Drilseach won the Saltire Society First Book of the Year Award in 2013. The sequel An Luingeas Dorcha air Fàire is contained in STEALL, the Gaelic magazine, published by CLÀR.
