Based on a concept by New York Times bestselling Diary of a Wimpy Kid author Jeff Kinney comes Poptropica, a brand-new graphic-novel series by Mitch Krpata and Kory Merritt that takes readers on an adventure beyond the incredibly popular online role-playing world.

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.

Following the epic penultimate conclusion of The Secret Society, Oliver, Mya, and Jorge find themselves at an impasse: The Protectors’ headquarters lie in ruins; the nefarious Octavian is nowhere to be found; and they have no idea how their tampering with the timeline of Poptropica might affect history. As our heroes band together to save the mysterious, uncharted island world and find a way home, they are reminded of crucial events from their pasts—including how they were transported to Poptropica in the first place. The trio suddenly finds itself in the heart of Poptropica, where the Protectors discover the nexus of all time and are offered the opportunity to see what their lives would be like if they could change just one thing from their pasts. But will they choose to go down these alternate paths? Filled with heart and humor, this is the breathtaking finale Poptropica fans have been waiting for.

In this exciting third installment of the Poptropica series, we find Mya, Oliver, and Jorge in the custody of a secret society whose mission is to protect and preserve Poptropica—a mysterious, uncharted island world. These Protectors, as they call themselves, believe that any outside interference with the islands of Poptropica could have catastrophic results on the course of history in the real world. As if things aren’t bad enough, Octavian has finally claimed possession of the confounding map, thwarted the society’s attempts to capture him, and is determined to alter the time line. The trio must join forces with the Protectors and find Octavian before he can go through with his evil plot, or all of human history might be changed—or worse—destroyed!
