Armchair Adventurers is a loosely organised virtual book club. Essentially it's a place to post recommendations and reviews of non-fiction books. My first suggestion to the group: The Lost City of Z by David Grann. I own this and print and am seriously going to break down and get it in audio for long car rides.
So if I continue to be lax about the BoTD, perhaps you can hit Armchair Adventurers for some recommended reading - just make sure you click the 'Armchair + Others' bubble, so you can see what other readers have recommended.
