Things on Ooo are looking dire! Between the flood of the Blood Banks, a newly resurrected Golb (live and in the flesh!), and Magic Man being, well, dare we say the worst—how can our heroes possibly pass this ultimate test?! Find out as writer Nick Winn (Silver Sprocket’s Bloody Mary) and artist John P Golden (Over the Garden Wall) flip the world of Adventure Time on its head! Golb is back and better than ever! Well—maybe not better. Or ever. The embodiment of chaos is threatening all of Ooo, and not even Ravine’s sick sword skills, Finn and Jake’s killer distractions, or BMO’s sweet beats can calm things down. But things get even worse when Betty and Magic Man decide to leave the crazy zaniness behind them once and for all—and Magic Man decides it’s time to start it over . . .The finale to writer Nick Winn's first acclaimed run is here! But rest assured—the new adventures that lie ahead will be doubly mathematical!
