Josephine (“Jo”) is a typical American kid navigating her way through middle school life and always learning something new. Little sister Alexa is also curious, but that isn’t necessarily a good thing. Alexa’s curiosity is more like mischief that gets her into trouble even though she doesn’t mean any harm. When Mom & Dad take Jo and Alexa on a trip to England to meet friends and learn English Christmas traditions, Jo records the whole journey in her journal. Everything.
