@George,
I started reading 4 at the same time on a recentish holiday
Station Eleven - Emily St. John Mandel (finished it - pretty good 4/5)
A Letter to Layla: Travels to Our Deep Past and Near Future - Ramona Koval (still only half way throught but really enjoying it (I find it hard to find time to long read when I'm not on vacation)
Moneyland: Why Thieves and Crooks Now Rule the World and How To Take It Back - Oliver Bullough (early on finding it a little heavy going)
Factfulness - Hans Rosling (hoping this gets better - author is a bit annoying at the start, not far enough in to make a call)
