"Spirit of the Wind" by Lew Freedman is the one I was talking about from the other thread. Along those lines though, there's a great book called "Soldiers & Sled Dogs ~ A History of Military Dog Mushing" by Charles L. Dean
"Longitude ~ The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time"
(by Dava Sobel). I can't recommend this one enough. Actually, Dava Sobel has written a few interesting books, this "Longitude" is my favorite though.
Honestly, the best for long manifests & long plane rides is something you don't necessarily want to ponder over though... just something to enjoy then toss back into your duffle bag... like any of the action novels by Clive Cussler. Any of his Dirk Pitt books are great.
Plus, if you go into the history section of any book store they've always got these quirkly little fact books that are great... like "Who's buried in Grant's Tomb?" which details the last words, manner of death, map & hours of the burial sites, etc. of each of the Presidents. That was a kind of cool book. I'd like to read one that is just like it... except entirely before their terms. But any of those quirky little history books are cool ~ because once you read it... something is bound to catch your eye & you can then look for another book to buy about whatever it is that you just read in the quirky book.
