Take up the torch and prepare for battle! With disaster at the door, Simon and Betty debate on whether or not they should leave Ooo, save themselves, and start fresh . . . on Mars! At the same time, Marceline takes up the mantle of Vampire Queen to help save the Candy Kingdom—and all of Ooo—from the rampaging floods of the Blood Banks, but even she seems to be powerless against Magic Man's brand of chaotic magic! What other adventurers could possibly stand a chance? It's time for Finn to ace this test and become the greatest hero of all time—and hopefully stop the end of the world as Ooo knows it in an all-new, all-epic chapter from writer Nick Winn (Bloody Mary) and stellar artist John P Golden (Over the Garden Wall)!
