A fascinating and salutary article about how life can sometime rob a writer. Mark Lawson, journalist, broadcaster, writer has had both fiction and non-fiction books snatched from him, half-written, by a variety of circumstances. In a his article he talks about each of these lost enterprises with modesty, humour and insight.

Green Writing Room 
A fascinating read. Thank you Hilary. Very comforting to read that many feel they are also writing stuff that might be unpalatable or inferior for publication. Writing words has a life of its own and once they are put down you can mull about it but the bones are there or not. Fleshing them out might help but nothing will change its original feel or timbre.
I love putting down words.
Me too!
