Not due out in the UK until this coming November, but certainly worth noting, is Franz Kafka's The Zurau Aphorisms (Harvill Secker). (the publisher information I have renders this "Zureau"; a dear friend tells me "Zürau" is best.) The only information I have, so far, comes straight from Amazon:
Franz Kafka spent eight months in Zurau between September 1917 and April 1918, enduring at his sister's house the onset of tuberculosis. Illness paradoxically set him free to write, in a series of philosophical fragments, his settling of accounts with life, marriage, his family, guilt and man's condition. These "aphorisms" will appear, sometimes with a few words changed, scattered across other writings (letters, diaries), some of which appeared as posthumous fragments only after his death in 1924. By chance, Roberto Calasso rediscovered the original notebooks as Kafka wrote them, in Oxford's Bodleian Library. Each thought or sequence of thoughts is set off on a separate page in counterpoint to the white space surrounding them. With a brief introduction and afterword by Calasso, the assemblage is a distillation of Kafka at his most powerful and enigmatic. It is a lost jewel that provides the reader with a fresh perspective on the collective work of a genius.
