Reading Level: Grades 8+

When 17-year-old Ginny's eccentric aunt died she sent her niece $1,000 and some numbered envelopes  with the instruction that Ginny fly to Europe by herself and follow the directions in the envelopes, never opening the next envelope until the tasks in the previous envelope were completed.

WARNING: If you have not read 13 Little Blue Envelopes read no more!

It was a summer Ginny would never forget. She worked her way through twelve of the envelopes before her backpack (which held the thirteenth envelope) was stolen in Greece. Resigning herself to never finishing the adventure, Ginny returns home to New York.

Months later she receives an e-mail from someone she doesn't know. The e-mail contains the first page of the thirteenth letter. When she answers the e-mail, the sender tells her the rest of the e-mail contains clues to another of her aunt's paintings. Clues that only Ginny can solve. The sender will not share the instructions in the letter unless Ginny agrees to accompany him on the hunt for the pieces of the work, sell the painting and split the proceeds with him 50/50.
