Disclosure: I dislike books that rely on dreams to get a point across. Also books that rely on coincidences to move the plot along. This had both, in spades. It also had a lot of uninteresting -- to me -- details about flying during WWII. The supernatural aspect was confusing and the ghost's purpose seemed really silly in the end. I did finish it, mainly because the writing was fine and I enjoyed the non-flying personal parts with the mother and son. The author mixes timelines (or maybe not) that muddied the whole story line. Too long at 300 pages, although skimming past the flying stuff helped speed up the read.
