New York Times bestselling author Maureen Johnson's fun, romantic, and hilarious sequel to her breakout hit 13 Little Blue Envelopes gets a brand-new cover! 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 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.
