A Marginal Sea is written from the vantage point of Ynys Môn/Anglesey, which is both on the edge of Wales and in a marginal sea of the Atlantic Ocean – the island is imagined here as a site of archipelagic connection with other places and histories, where the spaces of dream and digital technology are interwoven with the everyday. Skoulding's poems take their readers into new worlds: we come to terms with the oystercatcher's 'muscle of belonging'; we chart the cross-cultural coordinates of 'Newborough Warren with Map of Havana' ('and it's this way to the Malecón /to look out over the Menai Strait'); elegy and song overlap in moving poems which think through how we remember and misremember: 'it's my voice // deepening with others that won't let themselves / be buried.' ('Anecdote for the Birds'). A Marginal Sea is inventive, exhilarating in its soundscapes, and brilliantly awake to otherness, in language, and in the animal and natural world.
