Treasure from Lake Titicaca (The Mailbox Adventures)

Each story in The Mailbox Adventures takes young readers on an exciting action-packed journey to a place of the world not typically covered by elementary school geography. In this first book of The Mailbox Adventures series, a priceless ancient artifact is in jeopardy of being stolen, but Joey Jimmer-Jefferson has no idea. That is, until he is magically transported to the shore of the world's highest lake in South America through a mysterious mailbox found in the attic of his family's 200 year old Vermont farmhouse. How does the mailbox work, why did it pick him and how will he get back home? Joey needs to figure these questions out while he simultaneously tries to complete the task he has been thrust into: saving the priceless treasure from falling into the wrong hands. He will need more courage than he knew he had, and lots of quick thinking to outsmart the notorious Quizquiz Treasure Thieves.
