Pat thought being mayor was hard—but now, it’s more than just the village that’s in danger. Captain Cookie has been struck by a terrifying vision. He’s learned that if anyone dares disturb the Cookie Islands, it will trigger the destruction of all the realms of existence! And Jen has just found the final clue to find the islands by herself!

Now Pat and his friends have to go back to the Overworld, through the Nether, and to the Underworld to stop Jen and her sister EJ (Evil Jen) before they destroy everything! But finding Jen may be the easy part. As it turns out, the PopularMMOs team is being stalked by an old enemy who’s determined to get even with the pair. Pat and Jen may be the very ones leading a great evil straight to the Cookie Islands to destroy the world as they know it.

Will the friends be able to stop a plan of ultimate revenge—or will they wind up accidentally destroying everything?
