Ian Watson's brilliant debut novel was one of the most significant publications in British SF in the 1970s.

Intellectually bracing and grippingly written, it is the story of three experiments in linguistics, and is driven by a searching analysis of the nature of communication.

Fiercely intelligent, energetic and challenging, it immediately established Watson as a writer of rare power and vision, and is now recognized as a modern classic.
