Our annual dip into speculative fiction takes us to The Glitch, by Elizabeth Cohen, who has written a fast, funny, deeply hilarious debut about a high-profile, TED-talking, power-posing Silicon Valley CEO and mother of two who has it all under control, until a woman claiming to be a younger version of herself appears, causing a major glitch in her over-scheduled, over-staffed, over-worked life. We wish we could live so well, or do we?
