The Nix by Nathan Hill, 625 pages.
Well-reviewed book that ended up on a lot of best of the year lists. Hills book involves a boy whose mother leaves him when he is young. As an adult he is offered a chance to restart his life as an author, but only if he is willing to do a hatchet job on his long missing mother. He finds out the convoluted reasons for her leaving along the way. The writing style is very good and it was fun to read, but I didn't love the story.
