The Water Star by Philip Casey (Picador, £6.99 in UK)

This elegiac novel casts a gentle - but discerning - eye on the lives and loves of Irish and other exiles in a London shattered by the Blitz. Philip Casey brings the lyricism of a poet and the dramatic sense of a playwright to his tale of lost souls doing their best to glue their fragmented lives back together; his characters are vivid, subtly shaded, often tragic, but there's no wallowing in misery here - on the contrary, a life-affirming tenacity and humour, reinforced by an elegant cyclical structure and more than a hint of mysticism, makes The Water Star a pleasure to read. The final sequence, set in Ireland, chimes a little uncomfortably with the rest, but then comfort was never going to be a top priority in a book about alienation. An intelligent, memorable, moving novel.
