Desai, Kiran The Inheritance of Loss - Hamish Hamilton
Grenville, Kate The Secret River - Canongate
Hyland, M.J. Carry Me Down - Canongate
Matar, Hisham In the Country of Men - Viking
St Aubyn, Edward Mother’s Milk - Picador
Waters, Sarah The Night Watch - Virago
My bet is on Sarah Waters, but that's probably because it's the only book on the list I've read.
