In David Levithan’s New York Times bestseller Every Day, readers met A, a teen who wakes up every morning in a different body. A has made peace with that, even established guidelines by which to live: Never get too attached. Avoid being noticed. Do not interfere. It’s all fine until the morning that A wakes up in the body of Justin and meets Justin’s girlfriend, Rhiannon, and discovers what it means to wants to be with someone—day in, day out, day after day. In Another Day, readers experience the same story from Rhiannon’s perspective, as she seeks to understand A’s life and discover if you can truly love someone who is destined to change every day.
