Because of the sheer number of them, I've created a new category. Why not, after all?
David Montgomery surveyed over 50 people in the crime fiction world--writers, reviewers, knowledgeable fans--to give their Top 5 books of the year. He also collects some interesting stats from the contributions:
Most-cited book: Scott Phillips' Cottonwood -- 7 picks
Second most-cited book (tie): Ken Bruen's The Guards and T. Jefferson Parker's California Girl -- 6 picks each
Most-cited author: Ken Bruen -- 11 picks
Second most-cited author: T. Jefferson Parker -- 7 picks
Third most-cited author: Lee Child -- 6 picks
Most-cited debut book: J.A. Konrath's Whiskey Sour -- 3 picks
Most-cited unreleased book (tie): Kent Harrington's Red Jungle and Ray Banks' The Big Blind -- 2 picks each
Most-cited non-crime fiction book: Pete Dexter's Train -- 3 picks
Book I most wish I could have included: Laura Lippman's Every Secret Thing -- I read it last year, thus it wasn't eligible.
My own list is included as well, but considering I change my mind about every six seconds when it comes to this topic, take it for what it's worth.
