It's a bit cliche but I love the "best of the year" lists that mushroom at the end of the year.  Here are two:

Auren's book recommendations don't disappoint.  He's updated his favorites list with entries from 2014.

And, here's Seth Godin's.  Includes audio.

Finally, I should mention that my favorite non-fiction book this year was Ben Horowitz's "The Hard Thing About hard Things", and on the fiction side, "Sweet Tooth" by Ian McEwan, even though it was published in 2013.
