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 has found her bag. Finally Ginny can finish what she started. But instead of ending her journey, the last letter starts a new adventure, and Ginny finds she must hold on to her wits and her heart. This time there are no instructions.
