With a slowly growing 'library' courtesy of this thread, I would like to recommend one that I took a punt on - Mosquito Pathfinder by Albert and Ian Smith.
This is is the record of an NCO navigator who started on Wellingtons and then ended up on Pathfinder Mossies (clue's in the title I suppose...) and gaining a commission. What makes this one stand out for me is the different perspective Albert Smith brings to the narrative. He brings a personal touch, describing what might be thought of as more mundane aspects of everyday life but actually helps to paint a more fuller picture of WWII operational life. His description of Oboe Ops also makes one realise how technically advanced the RAF had become by the end of the war.
But what does one do with the books once read???
