EastCoastSail started this thread a while ago and it was great. I bought a number of the recommendations (Storm and Silence was one that I would never have known about).
www.seabreeze.com.au/forums/Sailing/General/Seeking-interesting-sailing-book-recommendationsI just finished Godforsaken Sea in paperback and Das Boot on Audible both of which I would recommend.
I'm sure ebay sellers pay less postage than you or I do so you might do as well on there.
