13 Little Blue Envelopes is by Maureen Johnson. Ginny is seventeen and getting ready for college. Suddenly she receives 13 envelopes from her recently deceased Aunt Peg, her crazy and free-spirited Aunt Peg, and finds herself on a plane to London with no idea what she will do when she gets there, except follow the instructions in the 13 little blue envelopes. A wonderful tale of adventure and self discovery.
