An Arbitrary Light Bulb by Ian Duhig; What the Earth Seemed to Say by Marie Howe; Collected Poems by Mimi Khalvati; Ceremony for the Nameless by Theresa Lola; Girl by Ruth PadelAn Arbitrary Light Bulb by Ian Duhig (Picador, £12.99)Among Duhig’s eclectic subjects are his Irish heritage, history, folklore, his home town of Leeds, marginalised figures, social and racial injustices, artists such as Jack B Yeats and Cecilia Vicuña, and poetic influences from Shakespeare to Roddy Lumsden. There is an encyclopedic knowledge and esoteric elusiveness within this book that invites exploration and promises revelation – a mystical hare writing “its own love in white ink on the snow, invisibly … a page awaiting the fall of darkness”. Multifarious and maverick, deeply personal and political, Duhig’s poetic vision alchemises the heart and mind. This is a brilliant collection from a balladeer of our times, a poet who stands for the people, always with a sense of compassion, humility and wry humour.What
