Out of the frying pan and into the Fire Kingdom! Hot on the trail of a mechanical imposter, Finn and Jake find themselves embroiled in yet another case of mistaken identity when Flame Princess accesses them by stealing her mother’s crown. And speaking of crowns—will Marceline’s efforts to reach Simon Petrikov finally pay off? Or is Ice King too far gone?!  Written by cartoonist and animator Nick Winn (Bloody Mary) and drawn by our next stellar artist, Agustin Morales (Go Go Proton, Megahrtz)—plus another mathematical backup story—'Handbook Heroes!' continues here!
