EDIT: Duplicate thread, sorry, didn't see the earlier one in PC Gaming.The bottom line, now, I'm afraid, is that as a late stage gall bladder cancer patient, I'm expected to live for 'several months' and it’s extremely unlikely I'll live beyond a year. So it looks like my latest novel, The Quarry, will be my last.
