Tyler has given you his list. Mine, in order of quality:
Kevin Laland, Darwin’s Unfinished Symphony.
Richard Bookstaber, The End of Theory.
Jonathan Haskel and Stian Westlake, Capitalism without Capital.
Aaron Ross Powell and Grant Babcock (eds.), Arguments for Liberty.
Tim O’Reilly, What’s the Future?
Note that Tyler and I both came out with books this year. His was The Complacent Class and mine was a new edition of The Three Languages of Politics.
I do not think our lists overlap at all, which is unusual. UPDATE: a commenter points out that Tyler and I both recommend Capitalism without Capital.
