This extravaganza of marvellous tales conjures a biography of mermaids and, in patterns of sometimes startling sounds and images, traces the fate of their race. It follows the paths and portals to another world, Land-Under-Wave, the realm of myth, imagination and the psyche. It is a book in touch and tune with the wellsprings of poetry. Work of the currently best know Irish-language poet, with English translations on facing pages by one of the best known poets in any language or country.
