I'm currently listening to 'Her Royal Spyness', a murder mystery with the main protagonist being a woman who is right on the edge of British royalty being the 34th person from the crown. The story is set in 1936 during the Prince Edward - Mrs. Simpson scandal. The reader has one of those wonderful voices I could listen to all day. This is the first book in a series and I am definitely ready to follow it up with the second book.
Before this I read 'Ready Player One', which I believe has been mentioned before. It is a sci-fi story set thirty years in the future, but it is really about 1980s geek and pop culture. I think you needed to be at least in your teens or twenties during the 1980s to get the nearly endless stream of trivia.
Two winners in a row. Hopefully the next book in my queue, 'The Red Pyramid' will be good, too.
