Based on a concept by Wimpy Kid author Jeff Kinney comes Poptropica, a brand-new graphic novel adventure series by Jack Chabert and Kory Merritt. In Mystery of the Map, 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!

Jack Chabert is a game designer for Poptropica, the creator and author of Eerie Elementary, and, writing under a different name, the author of more than 25 titles including licensed books for Adventure Time, Regular Show, Uncle Grandpa, and Steven Universe. Chabert lives in New York with his wife.

He is also the author of the online comic strip The Lost Side of Suburbia and the upcoming illustrated series The Dreadful Fate of Jonathan York. Merritt lives in Hammondsport, New York, where he teaches art for grades K–6.
