Ginny, 17, reads a letter from her free-spirited, unpredictable Aunt Peg, who has recently passed away. She is given several destinations, four rules, and the instruction to open one envelope upon her arrival at each place. Thus begins a rapid tour of Europe as the teen struggles to accomplish the tasks established by her aunt. The motivation: Ginny wants to understand the woman's wanderlust and, possibly, she just wants a connection to her beloved relative. Throughout her adventures in Rome, Paris, Greece, England, and the Netherlands, the teen collects pieces of Peg's past and learns more about her rapid departure. She also learns much about herself. The reason Ginny is sent to meet certain people is not always clear; sometimes she (and readers) wonder about the point of the exercise. Overall, though, the novel drives home the importance of family, love, and the value of connections that you make with people.
