Patrick Leigh Fermor: An Adventure by Artemis Cooper is the story of a under-funded toff who at the age of 19 in 1933 set off to walk from London to Istanbul.
The Third Reich at War: How the Nazis Led Germany from Conquest to Disaster is the third volume of Richard J. Evans's history of the great enormity, a project that's every bit as long as it needs to be.
H is for Hawk by Helen Macdonald told me more about the relationship between hawk and handler than I thought there was the remotest chance of me wishing to know.
Station Eleven by Emily St John Mandel starts off with an interesting premise but ends up reminding me that I prefer the way Stephen King did this kind of apocalyptic thing in The Stand.
The best thing I read on holiday was A Spy Among Friends: Philby and the Great Betrayal by Ben Macintyre. As a yarn it gets more amazing every time it's told. As a moral tale it makes you think even more as you get older. When you get older you understand the meaning of loyalty.
