A New York Times bestseller based on a concept by Wimpy Kid author Jeff Kinney, Mystery of the Map is the first book in Poptropica, a graphic novel adventure series by Jack Chabert and Kory Merritt.

Oliver, Mya, and Jorge take a ride in a hot-air balloon, only to crash-land on an unknown island filled with extinct animals and a horde of angry Vikings. Welcome to Poptropica, an uncharted group of islands whose existence is hidden from the rest of the world.

As the three friends embark on a perilous search for a way home, they quickly discover the shocking reason they were brought there—something that threatens the very existence of Poptropica and their ability to ever make it off the island!
