On hold for all the hot new books of 2015? In April, The Booklist Reader released this a well-crafted and researched list, All the Best Books of 2014, divided into 12 categories.
On their website, there a lot of posts devoted breaking down the master list into manageable chunks, such as historical fiction, or crime novels, etc. But, if you want to print out and sink your teeth into a meaty list, they also have an Excel document that you can download!
