I read a lot of great books last year, so I had a hard time choosing, but (fanfare, please!) the best book I read in 2014 was Jennifer Egan’s A Visit from the Goon Squad. It came out in 2010, but I didn't read it for years because the title misled me into thinking it was a different kind of book altogether. The goon in the title is time, and the main theme of this book is how time changes us, turns us into someone we wouldn't have recognized when we were young. This could be a real bummer of a theme, too, but the book is so smart and engaging that the theme just kind of washed over me because I was completely involved with its characters and delighted by its fine writing.
Goon Squad seems like more of a collection of short stories than a novel, at first, but the characters are connected to each other, sometimes very loosely. The narrative bounces around in time from about the 1970s into the 2020s and is mostly about people involved with the music and entertainment industry. There's a very moving PowerPoint presentation, a punk rock show at a club in LA in 1979, a celebrity journalist who tries to rape the starlet subject of his interview, a lion attack in Africa, and an erotic kiss delivered to the unwilling lips of a Mother Superior. Which is to say that this book is wildly entertaining on top of being incredibly, dazzlingly good.
