This looks to be a fairly representative collection of American publications, spanning a wide range of reading interests, from commercial (Amazon) to industry (Publisher's Weekly), critical (New York Times, Washington Post) and general (Vogue, Esquire). It even polls a couple of blogs for good measure (Book Riot, The Daily Beast). The results aren't too surprising: Hilary Mantel's Bring Up The Bodies was the most listed book, appearing on 9 of 14 fiction lists. Other titles mentioned several times were Billy Lynn's Long Halftime Walk by Ben Fountain (7), Gone Girl (6), This is How You Lose Her (5), and Arcadia (4). It looks like I agree so far with several of these choices, though I have yet to read Mantel.
