Ginny’s eccentric artist aunt dies and leaves her 13 sealed envelopes. The first one tells her to fly to London alone with only a backpack and some cash. She is not to communicate with anyone in the US and is to open each envelope in turn and follow its instructions. She meets people her aunt knew in London and Paris and travels to several other European cities over the course of the summer, following her aunt’s tracks and learning important things about herself in the process. A good summer read and vicarious travel narrative. Ginny is 17, so this book would be of most interest to high schoolers. Recommended.
