You know, it's not so much that while I'm on a plane I'll read something different than usual. It's more that I know I'm going to have a few hours with nothing to do but read, and no one will be interrupting me! I will always have the next book on my list ready to go though. The last trip I went on I started (and finished!) Heir of Fire, the fourth book in the super cool Throne of Glass series by Sarah J Maas.
I know what you mean. Just the thought alone to not have any distractions is awesome. I noticed that I tend to read more non-fiction on journeys (especially long journeys) - probably because there is little to disturb my reading. Last time I was on a long-haul flight back to the UK from Dubai, my choice o reading material ignited the most interesting discussion with an Indian gent sitting next to me about German politics of the 1960s. That was an unexpected bonus to the trip.
Yes, I think I have. It's London - and I think I may have to throw in a good old-fashioned cozy mystery - so, I'm thinking Christie, The Seven Dials Mystery.
It's sort of like Neverwhere, but with a more interesting protagonist.
