Good books

I'm going to be taking my own trip to South Africa in a few days.  Lots of time sitting in airplanes required.

So....anybody read any good books lately they'd recommend to soak up all the air time?  I just started the latest Robert Galbraith (J.K. Rowling) book, Lethal White.  It's good and it's long but I can tell I'm going to blitz through the last third or so of the book.

FYI.  I'm a fan of fiction and non-fiction books.

Thanks, MGoBoard.
