Based on a concept by New York Times bestselling Diary of a Wimpy Kid author Jeff Kinney, Poptropica, a graphic-novel series by Mitch Krpata and Kory Merritt, takes readers on an adventure beyond the incredibly popular online role-playing world. In book two, The Lost Expedition, Oliver, Mya, and Jorge continue their search for home, with a few hilarious stops along the way. As the friends set sail for new sights, they find the evil Octavian is still hot on their trail, and he's determined to get his hands on their magical map. To make matters worse, a mysterious organization is keen on expelling the three friends from Poptropica. As the pals travel, they find that each island is filled with its own unique brand of peril, and the mystery surrounding the map and Poptropica itself begins to unfold.
