The Last Little Blue Envelope (Paperback)
Ginny Blackstone spent last summer traveling around Europe, following the tasks her aunt laid out in a series of letters before she died. When someone stole Ginny's backpack and the last little blue envelope inside she resigned herself to never knowing how the adventure was supposed to end.
Now a mysterious boy has contacted Ginny from London, saying he's found her bag. Finally she can finish what she started. But instead of ending her journey, the last letter starts a whole new one, and Ginny must hold on to her wits . . . and her heart. This time, there are no instructions.
