NEVER WANTED TO KNOW ABOUT ADVENTURE TIME!
Written by Lord of Evil Himself, Hunson Abadeer (a.k.a Marceline the Vampire Queen's dad) to instruct and confound the citizenry of the Nightosphere, Adventure Time Encyclopædia is perhaps the most dangerous book in history. Although seemingly a guidebook to the Land of Ooo and its post-apocalyptic inhabitants, it is in fact an amusing nightmare of literary pitfalls, bombastic brain-boggles and ancient texts designed to drive the reader mad. Complete with secret lore and wizard spells, fun places you should visit and places where you will probably die, advice on whom to marry and whom not to marry, how to make friends and how to destroy your enemies--this volume includes hand-written marginalia by Finn, Jake, and Marceline. Arguably the greatest encyclopedia ever written since the beginning of the cosmos, it is also an indispensable companion to humans and demons who know what time it is.
