In retrospect, perhaps should have put a little more research into the holiday reads before I left.
Note that links almost certainly contain spoilers.
+ The Candy House -> A Visit from the Goon Squad: Jennifer Egan
+ A Separation: Katie Kitamura
+ Oh William! -> My Name is Lucy Barton: Elizabeth Strout
+ Sea of Tranquility: Emily St John Mandel
I would very much benefit from not reading the reviews of randoms who undoubtedly have wildly different tastes to me, stop overthinking/over-researching and just make a selection.
Of course your recommendations are most welcome!
